Gas is widely used both in industry, including chemical (for example, raw materials for the production of plastics) and in everyday life. In domestic conditions, gas is used for heating residential private and apartment buildings, cooking, heating water, as fuel for cars, etc.

From an environmental point of view, gas is one of the cleanest fuels. Compared to other types of fuel, it has the lowest amount of harmful emissions.

But if we talk about gas, we automatically mean natural gas extracted from the bowels of the earth.

One day I came across an article in the newspaper that told how one grandfather put together a simple installation and gets gas from manure. This topic interested me very much. And I would like to talk about this alternative to natural gas - biogas. I believe that this topic is quite interesting and useful for ordinary people and especially farmers.

On the farmstead of any peasant farm, you can use not only the energy of wind, sun, but also biogas.

Biogas- gaseous fuel, a product of anaerobic microbiological decomposition of organic substances. The technology for producing gas is an environmentally friendly, waste-free method of processing, recycling and disinfection of various organic wastes of plant and animal origin.

The raw materials for producing biogas are ordinary manure, leaves, grass, in general, any organic waste: tops, food waste, fallen leaves.

The resulting gas, methane, is the result of the vital activity of methane bacteria. Methane, also called swamp or mine gas, makes up 90-98% of natural gas, which is used in everyday life.

The installation for gas production is very simple to manufacture. We need a main container, you can cook it yourself or use some ready-made one, it can be anything. Thermal insulation must be installed on the sides of the container to use the unit in the cold season. We make a couple of hatches on top. From one of them we connect tubes for gas removal. For an intensive fermentation process and gas release, the mixture must be stirred periodically. Therefore, you need to install a mixing device. Next, the gas must be collected and stored or used for its intended purpose. To collect gas, you can use a regular car chamber, and then, if you have a compressor, compress it and pump it into cylinders.

The principle of operation is quite simple: manure is loaded through one hatch. Inside, this biomass is decomposed by special methane bacteria. To make the process more intense, the contents need to be stirred and preferably heated. For heating, you can install tubes inside through which hot water should circulate. The methane released as a result of the vital activity of bacteria enters the car chambers through tubes, and when a sufficient amount accumulates, it is compressed using a compressor and pumped into cylinders.

In warm weather or when using artificial heating, the installation can produce a fairly large amount of gas, about 8 m 3 / day.

It is also possible to obtain gas from household waste from landfills, but the problem is the chemicals used in everyday life.

Methane bacteria are found in the intestines of animals and, therefore, in manure. But in order for them to start working, it is necessary to limit their interaction with oxygen, since it inhibits their vital functions. That is why it is necessary to create special installations so that bacteria do not come into contact with air.

In the resulting biogas, the concentration of methane is slightly lower than in natural gas, therefore, when burned, it will produce slightly less heat. When burning 1 m 3 of natural gas, 7-7.5 Gcal is released, then when burning biogas - 6-6.5 Gcal.

This gas is suitable both for heating (we also have general information about heating) and for use in household stoves. The cost of biogas is low, and in some cases practically equal to zero, if everything is made from scrap materials and you keep, for example, a cow.

The waste from gas production is vermicompost - an organic fertilizer in which, during the process of decay without access to oxygen, everything from weed seeds rots, and only useful microelements necessary for plants remain.

There are even methods for creating artificial gas deposits abroad. It looks like this. Since a large proportion of discarded household waste is organic matter, which can rot and produce biogas. In order for the gas to begin to be released, it is necessary to deprive organic matter of interaction with air. Therefore, the waste is rolled up in layers, and the top layer is made of a gas-waterproof material, such as clay. Then they drill wells and extract gas as if from natural deposits. And several problems are being solved at the same time, such as waste disposal and energy generation.

Under what conditions is biogas produced?

Conditions for obtaining and energy value of biogas

In order to assemble a small-sized installation, you need to know from what raw materials and by what technology biogas can be obtained.

Gas is obtained during the decomposition (fermentation) of organic substances without access to air (anaerobic process): domestic animal droppings, straw, tops, fallen leaves and other organic waste generated in individual households. It follows that biogas can be obtained from any household waste that can decompose and ferment in a liquid or wet state.

The decomposition (fermentation) process takes place in two phases:

1. Biomass decomposition (hydrotation);
2. Gasification (biogas release).

These processes occur in a fermenter (anaerobic biogas plant).

The sludge obtained after decomposition in biogas plants increases soil fertility and productivity increases by 10-50%. Thus, the most valuable fertilizer is obtained.

Biogas consists of a mixture of gases:

• methane-55-75%;
• carbon dioxide - 23-33%;
• hydrogen sulfide-7%.

Methane fermentation is a complex process of fermentation of organic substances - a bacterial process. The main condition for this process to occur is the presence of heat.

During the decomposition of biomass, heat is generated, which is sufficient for the process to proceed; in order to retain this heat, the fermenter must be thermally insulated. When the temperature in the fermenter decreases, the intensity of gas evolution decreases, since microbiological processes in the organic mass slow down. Therefore, reliable thermal insulation of a biogas plant (biofermenter) is one of the most important conditions for its normal operation. When loading manure into the fermenter, it must be mixed with hot water at a temperature of 35-40 o C. This will help ensure the necessary operating mode.

When reloading, heat loss must be minimized. Engineering assistance for biogas

For better heating of the fermenter, you can use the “greenhouse effect”. To do this, a wooden or light metal frame is installed above the dome and covered with plastic film. The best results are achieved at a temperature of the raw material that is fermented at 30-32°C and a humidity of 90-95%. In the regions of the middle and northern zone, part of the gas produced must be spent during the cold periods of the year on additional heating of the fermented mass, which complicates the design of biogas plants.

Installations are easy to build on individual farms in the form of special fermenters for fermenting biomass. The main organic raw material for loading into the fermenter is manure.

When loading cattle manure for the first time, the fermentation process must last at least 20 days, and for pork manure at least 30 days. You can get more gas when loading a mixture of various components compared to loading, for example, cattle manure.

For example, a mixture of cattle manure and poultry manure, when processed, produces up to 70% methane in biogas.

After the fermentation process has stabilized, you need to load raw materials every day with no more than 10% of the amount of mass processed in the fermenter.

During fermentation, in addition to the production of gas, organic substances are disinfected. Organic waste gets rid of pathogenic microflora and deodorizes unpleasant odors.

The resulting sludge must be periodically unloaded from the fermenter; it is used as fertilizer.

When the biogas plant is first filled, the extracted gas does not burn, this happens because the first gas produced contains a large amount of carbon dioxide, about 60%. Therefore, it must be released into the atmosphere, and after 1-3 days the operation of the biogas plant will stabilize.

Table No. 1 - the amount of gas obtained per day during the fermentation of excrement of one animal

In terms of the amount of energy released, 1 m 3 of biogas is equivalent to:

• 1.5 kg of coal;
• 0.6 kg kerosene;
• 2 kW/h of electricity;
• 3.5 kg of firewood;
• 12 kg of manure briquettes.

Design of small-sized biogas plants

Figure 1 - Diagram of the simplest biogas plant with a pyramidal dome: 1 - pit for manure; 2 - groove - water seal; 3 — bell for collecting gas; 4, 5 - gas outlet pipe; 6 - pressure gauge.

According to the dimensions shown in Figure 1, pit 1 and dome 3 are equipped. The pit is lined with reinforced concrete slabs 10 cm thick, which are plastered with cement mortar and coated with resin for tightness. A bell 3 m high is welded from roofing iron, in the upper part of which biogas will accumulate. To protect it from corrosion, the bell is periodically painted with two layers of oil paint. It is even better to first coat the inside of the bell with red lead. In the upper part of the bell, a pipe 4 is installed to remove biogas and a pressure gauge 5 is installed to measure its pressure. The gas outlet pipe 6 can be made of a rubber hose, plastic or metal pipe.

Around the fermenter pit, a concrete groove is installed - a water seal 2. filled with water, into which the lower side of the bell is immersed 0.5 m.

Figure 2 - Device for condensate removal: 1 - pipeline for gas removal; 2 - U-shaped pipe for condensate; 3 - condensate.

Gas can be supplied, for example, to a kitchen stove through metal, plastic or rubber tubes. To prevent the tubes from freezing due to the freezing of condensing water in winter, use a simple device shown in Figure 2: a U-shaped tube 2 is connected to pipeline 1 at the lowest point. The height of its free part must be greater than the biogas pressure (in mm water column). Condensate 3 is drained through the free end of the tube, and there will be no gas leakage.

Figure 3 - Diagram of the simplest biogas plant with a conical dome: 1 - pit for manure; 2 — dome (bell); 3 — expanded part of the pipe; 4 - gas outlet pipe; 5 - groove - water seal.

In the installation shown in Figure 3, pit 1 with a diameter of 4 mm and a depth of 2 m is lined inside with roofing iron, the sheets of which are tightly welded. The inner surface of the welded tank is coated with resin for anti-corrosion protection. On the outside of the upper edge of the concrete tank, a circular groove 5 up to 1 m deep is installed, which is filled with water. The vertical part of the dome 2, covering the tank, is freely installed into it. Thus, the groove with water poured into it serves as a water seal. Biogas is collected in the upper part of the dome, from where it is supplied through the outlet pipe 3 and then through pipeline 4 (or hose) to the place of use.

About 12 cubic meters of organic mass (preferably fresh manure) is loaded into round tank 1, which is filled with the liquid fraction of manure (urine) without adding water. A week after filling, the fermenter starts working. In this installation, the fermenter capacity is 12 cubic meters, which makes it possible to build it for 2-3 families whose houses are located nearby. Such an installation can be built on a farmstead if the family raises, for example, bulls or keeps several cows.

Figure 4 - Schemes of variants of the simplest installations: 1 - supply of organic waste; 2 - container for organic waste; 3 - gas collection area under the dome; 4 - gas outlet pipe; 5 - sludge drainage; 6 — pressure gauge; 7 — dome made of polyethylene film; 8 - water seal and; 9 — cargo; 10—one-piece glued polyethylene bag.

The design and technological diagrams of the simplest small-sized installations are shown in Figure 4. The arrows indicate the technological movements of the initial organic mass, gas, and sludge. Structurally, the dome can be rigid or made of polyethylene film. A rigid dome can be made with a long cylindrical part for deep immersion in the processed mass, floating, Figure 4, d, or inserted into a hydraulic seal, Figure 4, e. A film dome can be inserted into a hydraulic seal, Figure 4, e, or made in the form of a seamlessly glued large bag, Figure 4 , and. In the latter version, a weight 9 is placed on the film bag so that the bag does not swell too much, and also to create sufficient pressure under the film.

The gas, which is collected under the dome or film, is supplied through a gas pipeline to the place of use. To avoid a gas explosion, a valve adjusted to a certain pressure can be installed on the outlet pipe. However, the danger of a gas explosion is unlikely, since with a significant increase in gas pressure under the dome, the latter will be raised in the hydraulic seal to a critical height and will tip over, releasing the gas.

Biogas production may be reduced due to the fact that a crust forms on the surface of the organic raw material in the fermenter during fermentation. To ensure that it does not interfere with the escape of gas, it is broken by mixing the mass in the fermenter. You can mix not by hand, but by attaching a metal fork to the dome from below. The dome rises in the hydraulic seal to a certain height when gas accumulates and lowers as it is used.

Thanks to the systematic movement of the dome from top to bottom, the forks connected to the dome will destroy the crust.

High humidity and the presence of hydrogen sulfide (up to 0.5%) contribute to increased corrosion of metal parts of biogas plants. Therefore, the condition of all metal elements of the fermenter is regularly monitored and damaged areas are carefully protected, preferably with lead lead in one or two layers, and then painted in two layers with any oil paint.

Figure 5. Diagram of a heated biogas plant: 1 - fermenter; 2 — wooden shield; 3 - filler neck; 4 — methane tank; 5 - stirrer; 6 — branch pipe for biogas selection; 7 - thermal insulation layer; 8 - grate; 9 - drain valve for processed mass; 10 — channel for air supply; 11 - blower.

Biogas plant with heating of the fermented mass with heat , released during the decomposition of manure in an aerobic fermenter, is shown in Figure 5. It includes a digester tank - a cylindrical metal container with a filler neck 3. a drain valve 9. a mechanical stirrer 5 and a nozzle 6 for biogas selection.

Fermenter 1 can be made rectangular and 3 wooden materials. For unloading processed manure, the juice walls are removable. The floor of the fermenter is lattice; air is blown through the technological channel 10 from a blower 11. The top of the fermenter is covered with wooden sheets 2. To reduce heat loss, the walls and bottom are made with a heat-insulating layer 7.

The installation works like this. Pre-prepared liquid manure with a moisture content of 88-92% is poured into the methane tank 4 through the head 3, the liquid level is determined by the lower part of the filler neck. Aerobic fermenter 1 is filled through the upper opening part with bedding manure or a mixture of manure with loose dry organic filler (straw, sawdust) with a moisture content of 65-69%. When air is supplied through the technological channel in the fermenter, the organic mass begins to decompose and heat is released. It is enough to heat the contents of the methane tank. As a result, biogas is released. It accumulates in the upper part of the digester tank. Through pipe 6 it is used for domestic needs. During the fermentation process, the manure in the digester is mixed with a mixer 5.

Such an installation will pay for itself within a year only due to waste disposal in personal households. Approximate values ​​for biogas consumption are given in Table 2.

Table No. 2 – approximate values ​​for biogas consumption

Note: the installation can operate in any climate zone.

Individual biogas plant (IBGU-1) for a family with 2 to 6 cows or 20-60 pigs, or 100-300 poultry (Figure 6). The installation can process from 100 to 300 kg of manure every day and produces 100-300 kg of environmentally friendly organic fertilizers and 3-12 m 3 of biogas.

Modern society is increasingly trying to use alternative sources of electrical energy, this helps to cope with the problem of resource conservation in the world, and also allows us to minimize costs for this or that type of work. To achieve their goals, people have adapted to using the energy of natural elements: water, wind, soil, sun, and in addition to using non-standard types of fuel, which easily replace traditional ones.

A biogas plant for your home will allow you to obtain the source of energy produced – biogas – on your own. This fuel will find its application in the everyday life of any person. Let’s figure out what the main advantages of this design are, for what purposes it can be used, and how to make a simple biogas plant with your own hands.

Application area

What is such a device used for? For the production of ecological fuel, biogas, which can be used on farms, in everyday life, and in enterprises.

Biogas can be used to generate heat, electricity, and as automobile fuel. The configuration and content of the installation has many variations, depending on the power required for each specific case, the type of primary raw materials used and the final product obtained. On the Internet you can study various photos of biogas plants that differ from each other in certain parameters.

The operating principle of a biogas plant is extremely clear, so its use is permissible always and everywhere. The main factor influencing the need and feasibility of setting up a unit at a certain location is the provision of a sufficient volume of organic raw materials for work, which will be needed in the process.

How does it work

In order to understand the principle of operation, it is necessary to understand the structure of a biogas plant. A standard unit includes the following components, parts and parts:

• container for primary organic raw materials;
• crushers of too coarse material (various mixers, mills), allowing to obtain smaller fractions of raw materials;
• gas holder – a container in which produced biogas is accumulated;
• reservoir, container, reactor where the fuel production process is carried out;
• tubes through which primary raw materials are delivered to the biofuel production tank;
• a system that allows you to transfer biogas from the reservoir to the gas tank and to the next stages of processing;
• automated systems, security and process control systems.

To become more familiar with the structure of the unit, you can study the diagrams and drawings of biogas plants, which will clearly display all the components and components of the equipment.

The principle of operation is based on fermentation and subsequent decomposition of the initial raw materials (which can be various agricultural or industrial wastes, for example, manure, forest products) in the bioreactor of the installation. This process occurs under the influence of special bacteria.

As a result of the processes carried out in the reservoir, biogas is produced, consisting of methane, hydrogen sulfide, CO2, ammonia, N, etc.

The main stages of the processes occurring in the device:

• supply of organic raw materials in containers;
• grinding and further transportation of loaded waste into the reactor, simultaneous heating of the biomass;
• the beginning of the decomposition process in a sealed bioreactor, the ideal temperature for its operation: + 40 degrees Celsius;
• formation of biogas (in a gas holder) and biofertilizer (in a special separate reactor tank);
• the entry of biogas into the purification system and its further intended use by humans (for household consumption, heat or electricity generation);
• use of biofertilizer from the reactor for its intended purpose.

How to do it yourself

A biogas plant for farming or household use can be made by a person who has the necessary tools, knowledge of plumbing and basic welding skills.

The sequence of actions taken will be as follows:

• manufacturing the body of the bioreactor, which is used to carry out fermentation (the container can be made of metal or concrete);
• installation of covers on top of the tank, holes in the side walls necessary for loading and, accordingly, unloading raw materials;
• installation of a gas tank;
• construction of a pipeline from the gas tank to the place of consumption of the final product (this design must include valves and protective elements - various valves, valves, etc.).

Installing a biogas plant at a dacha, in a country house, on a farm, or in production will allow you to receive not only economic benefits, but also achieve other positive results, namely in the environmental and energy aspects.

Using such a device, the consumer will not only receive environmentally friendly fuel, several types of energy and biological fertilizer, but will also significantly reduce the opportunity costs that could have been incurred in the absence of such a unit.

Hello to all readers and visitors of the “build a house” blog. I remember in one of the articles where we “invented”, I promised to tell you about getting biogas at home. Well, you promised, so you have to fulfill it, so as not to be sent to one of the bad places.

What do we know about the biogas plant? At the moment, many have only a vague idea about this, and most do not know anything at all about what it is - the whole idea of ​​\u200b\u200bsupplying energy to your home comes down to paying bills for gas or other energy resources on time. However, the endless increase in energy costs is prompting some inquisitive minds to look for alternative solutions and look for production methods, for example equipment for producing biogas at home from organic waste. Moreover, there are also Kulibins who manage to make 2 in 1 at once - combine a septic tank with a biogas plant. Do you think it's a joke? Not at all. In our world this is not possible.

So, a biogas plant will provide not only cheap energy for cooking and heating the house, but also high-quality fertilizer.

Home biogas plant using manure - diagram

The production of biogas from waste is an environmentally friendly type of fuel. In terms of its characteristics, it is practically in no way inferior to natural gas. It’s just that it’s not extracted from the ground, but by fermentation of organic waste.

The technology for extracting biogas can be imagined as follows: in a special collection facility called a bioreactor, the process of processing and fermenting waste is carried out. As a result, a mixture of gases is released, consisting of 60% methane, 35% carbon dioxide and the remaining 5% other gaseous substances. The extracted gas is constantly removed from the bioreactor and, after purification, is used for domestic purposes.

Diagram of the operating principle of a biogas plant

Waste waste, turned into first-class fertilizer, are periodically extracted and transported to the fields.

Note: studies have shown that a field treated with fertilizers fermented anaerobically gives a yield 20-30% more than a field fertilized in the usual way.

Biogas plants for home – buy or make it yourself?

If large farmers can afford to buy a biogas installation created in industrial conditions, then small enterprises, and even more so private homeowners, will most likely be able not to buy, but to install with their own hands less powerful installations that operate according to the same method, from scrap materials. But first you need to understand exactly what size, and most importantly what type of installation you want to get on your site.

Installation diagram for producing biogas for enterprises, farms

Types of installations, like the types of fermentation of organic substances, there are only two - with the supply of air (aerobic) and without it (anaerobic). At aerobic fermentation During the decomposition of biomass, hydrogen is oxidized to water, and carbon to carbon dioxide. Moreover, at this moment a large amount is released - the fermenting biomass heats up greatly.

During anaerobic fermentation 60-70% of carbon turns into methane, and the rest of it - into hydrogen, carbon dioxide and nitrogen. A regular gas burner is well suited for burning methane.

Biogas plant near the collective farm barn

The aerobic method of obtaining energy is easier and simpler than the anaerobic method. It does not require the production of sealed fermentation chambers and control. Aerobic installations are called BTS(biothermal stations). And anaerobic - BES(bioenergy or biogas stations). Any organic agricultural product is suitable as a raw material for fermentation. One Israeli company, for example, presented a compact biogas production plant that operates exclusively on fruit and vegetable peelings.

Home biogas plant from HomeBioGas

The biogas installation developed by the Israeli company HomeBioGas for producing gas at home, with its modest dimensions (123 x 165 x 100 cm) and weighing no more than 40 kg, can ensure the operation of one tile burner at maximum heat for an hour.

Homebiogas - biogas plant of an Israeli company

In addition, this installation produces up to 8 liters liquid fertilizers per day at maximum tank load (6 kg).

It is estimated that one small agricultural enterprise can process about a ton of organic waste per year using this installation. True, the installation is designed to operate at an average daily temperature of +20 o C. I, however, want to tell you how to create a home biogas installation that works perfectly in the climatic zone of central Russia. In principle, there is nothing particularly complicated about it.

Home biogas station

If the owners of the installation want it to produce 0.7-0.9 m 3 of biogas every day (quite enough to cook food for two people), then they need to do the following.

1. Load a fermentation chamber with a volume of 1 m3 with finely chopped organic waste diluted in water (let me remind you - fruit and vegetable peelings) in a weight ratio of 1: 10 - 1: 5.
2. Close it hermetically and ensure constant temperature supply from +25 to +30°C.

To maintain a constant temperature in the chamber, through it it is necessary to run the hot water coil, heated by gas produced by the same installation. Two taps need to be installed on the gas pipeline line: one at the gas stove, the other at the outlet of the reactor.

Note: our savvy rural people have long been thinking, and some have put it into practice, to obtain gas for heating the house from their own feces - that is, they combine a septic tank with a biogas plant. If you search the Internet well, you can even find diagrams.

Gas collector or gas holder- the second most important element of a biogas plant, after the fermentation plant. It consists of two steel vessels (one of which is turned upside down), easily entering each other. Water is poured into the outer vessel, forming a hydraulic seal for biogas entering the cavity of the inverted vessel. The annular gap between the walls of the vessels is approximately 50 mm. You can connect both tanks using ½-inch diameter pipes. The same gas pipeline takes gas from an inverted vessel and delivers methane to a conventional gas stove. It is recommended to cover the outside of the gas holder with an insulated tent.

Biogas is a completely new source of energy. Using it, you can simply forget about the hated electricity tariffs.

The simplest example of biogas is the gas that is released when manure or other household waste rots.

How to make a biogas plant with your own hands?

The process of creating a biogas plant with your own hands is quite labor-intensive, but possible. This setup will help save your money: now you don't need to buy fuel and electricity, you will produce it yourself.

You can also recreate a future installation using available materials. For example, the reactor of a future installation can be made from old pots, basins, and leftovers. It is best to choose cylindrical objects.

The main requirements that any reactor must meet:

• hydro and air tightness. If biogas and ordinary air are mixed, a reaction will occur, the force of which can easily break the reactor at best, and explode it at worst;
• excellent thermal insulation;
• be durable and reliable, because during the reaction a huge amount of energy is released.

To build a good bio-installation, you need to adhere to the following sequence:

• choose a location for the future rector and calculate the daily waste rate to determine the size of the reactor;
• prepare the basin and install the unloading and loading pipes;
• install and securely secure the loading hopper and gas outlet pipe;
• for use, maintenance and repair of the unit, install the hatch cover;
• thoroughly check the reactor for leaks and thermal insulation;

It is best to make the walls of the future installation from concrete, since the strength of your reactor is the key to safety.

It is also important that the distance to the nearest residential building is at least 500 meters. This measure is due to the fact that during the fermentation process poisonous gas is released, which can kill a person in a matter of minutes.

It should be remembered that biogas is an explosive product, and in the event of an explosion it will destroy everything within a radius of 200-300 meters.

To obtain the biogas itself, you need:

1. mix about 2 tons of cow manure and 4.5 tons of humus in the form of rotten leaves, tops, and waste.
2. add water so that the humidity in the reactor is at 60-70% humidity;
3. Load the resulting mass into the pit and use a heating unit (coil) to heat it to 35-40 degrees. After this, the mixture itself will begin to ferment and in an anaerobic environment it will warm up to 70 degrees;
4. attach a counterweight to the dome, the weight of which should be 1.5-2 times greater than the mixture itself, this is done so that the dome does not fly off the pit during the reaction process.

5.5-6 tons of mixture will be enough for a biogas plant to operate for six months.

Remember that the mass you load into the reactor should not contain antibiotics, dyes, solvents or other synthetic substances. Otherwise, they will not only interfere with the entire reaction and stop it, but also ruin the walls of your reactor.

As can be noted, the operating principle of a biogas plant is very simple. Simply put, they install in the pit sealed tank where raw materials are stored for processing. Having loaded them, you just have to wait until the microorganisms, they are the ones who ensure the entire process, decompose the mass, and only after that you can collect the finished gas.

Fermented raw materials can also be used. You can easily use it in agriculture as fertilizer.

After the gas has been produced, it remains in the reactor when the mass is removed from the reactor through the discharge pipe. It is very important that the volume of the temporary storage tank is no less than the reactor.

Anyone can create biogas on their own. This does not require special knowledge or special skills in the field of renewable energy sources. If every person thinks about the world around them, the environmental situation on Earth will improve significantly.

Manure gas is a reality. It can actually be obtained from manure, which somehow fertilizes the land. But you can put it into circulation and get real gas.

To obtain gas from manure with your own hands at home, a farm biogas installation is used. You can produce natural gas using a digester right on the farm. This is how many farmers produce. You don't need to purchase special fuel for this. Enough natural raw materials.

The bioreactor should contain from 1 to 8-10 cubic meters. private production waste, chicken manure. Production and processing of raw materials on a device with such a volume will be able to process more than 50 kg of manure. To make a biogas installation, you should find the drawings according to which the equipment is made, and you also need a diagram.

The installation is carried out in several stages:

Mixing of raw materials;

Heating;

Biogas release.

A homemade installation will allow you to obtain gas from manure in a matter of time. You can assemble it yourself, having diagrams and drawings. For the heat generator, you can choose boilers for heating water. To collect gas on site, a gas tank is needed. It collects and stores gas.

Remember that impurities and debris in the tank must be cleaned from time to time.

You can obtain gas from manure using a biogas plant. You can design it yourself. Determine the volume of raw materials to be processed, select a suitable container in which the raw materials will be processed and mixed - this is how gas saturated with methane in biofuel is produced.

Making biogas at home

There is a stereotype that biogas can only be obtained in specialized industries and farms. However, it is not. Today you can make biogas at home.

Biogas is a combination of various gases that are created by the decomposition of organic substances. It is worth knowing that biogas is flammable. It ignites easily with a clean flame.

Let us note the advantages of a biogas installation at home:

1. Producing biogas without expensive equipment;
2. Using your ;
3. Natural and free raw materials in the form of manure or plants;
4. Caring for the environment.

Having a biogas installation at home is a profitable business for the owner of a summer cottage. To make such an installation, you need a small amount of money: two 200-liter barrels, a 50-liter barrel, sewer pipes, a gas hose and a tap.

As you can see, to do the installation yourself, you don’t even need to buy additional tools. Barrels, taps, hoses and pipes can almost always be found on the farms of dacha owners. A gas generator is a concern for the environment, as well as your opportunity to use an alternative source of energy and fuel.

Why do you need a biogas plant for farming?

Some farmers, summer residents, and owners of private houses do not see the need to build a biogas installation. At first glance, this is true. But then, when the owners see all the benefits, the question of the need for such an installation disappears.

The first obvious reason to install a biogas plant on a farm is to obtain electricity and heating, which will allow you to pay less for electricity.

Using your own energy costs less than paying to supply it to the farm.

Another main reason for the need to create an installation is the organization of a complete waste-free production cycle. We use manure or litter as raw materials for the device. After processing we get new gas.

The third reason in favor of a biogas plant is its efficient processing and environmental impact.

3 advantages of a biogas plant:

• Generating energy to keep the family farm running;
• Organization of a complete cycle;
• Efficient use of raw materials.

Having an installation on your farm is an indicator of your efficiency and concern for the environment. Biogenerators save a huge amount of money, ensuring waste-free production, efficient distribution of resources and raw materials, but also your complete self-sufficiency.

Methane is the main component of biogas. Biogas itself is a mixture of various gases. Among them, methane is the most important.

Let us highlight the factors that influence methane production:

• Environment;
• High-quality raw materials;
• Frequency of mixing of raw materials in the installation tank.

The raw materials in the container should be mixed with a pitchfork at least once a day, ideally six times.

The production of methane is directly related to the production of biogas. The better you treat the process of producing biogas, the better quality of biogas you will get at the output. To do this, you need to use only high-quality raw materials, monitor the place where the installation is located, and mix the contents of the tank. Then you will get methane correctly.
