A lot of biogas can be produced in a biogas digester, but the gas cannot be burned, why?

There are many reasons why biogas cannot be burned, from what you said, it is 1, the fermentation raw materials are insufficient (the use time has not been used for a long time) 2, the gas production is not lit soon, indicating that the fermentation raw materials have changed, so that the pH value is too high or too low, take a look at the biogas slurry with a test paper. 3. Add toxic substances when adding new fermentation raw materials (such as manure containing peppers, garlic, onions, pesticides, antibiotics, etc.) 4. You can solve the problem as long as you know the fermentation principle (fermentation principle: organic fermentation raw materials (fresh manure, straw, etc.), anaerobic conditions, 30% inoculum (raw materials containing methane bacteria), pH value in nitrogen and carbon 25-30:

1. The fermentation concentration is 6%-20%, the fermentation temperature is 12-55 degrees, and the infeed and outlet are (how many raw materials are produced).

A lot of gas is produced in the digester, not methane-containing biogas or the content is still very small, but non-combustible gases such as water vapor and carbon dioxide.

If your biogas digester is a new feed, 1. There is a problem with the raw materials that are fed, and the raw materials contain antibiotics, etc. 2. The raw materials are not acidified and directly enter the biogas digester, and there is too little inoculum in the biogas digester. The inoculum is not active.

It is still dormant. 3. The liquid in the biogas digester is acidified, and the one-time feeding is too much and the concentration is too high.

If your biogas ignition does not catch fire, let the gas out, the gas smells of rotten eggs, it means that it is running normally, and it is OK to do so several times. If there is no rotten egg smell, the digester is acidified or the raw material is defective.

It is necessary to add miscellaneous manure, if it is new, the methane content is not high, and the miscellaneous gas and moisture need to be removed. The old biogas digester indicates that there is too much biogas residue, so it is necessary to extract part of the manure and add new material, preferably mud and wood and grass ash.

You first test whether it can support combustion, check if there are air leaks, and those equipment that you are concerned about.

If a ton of chicken manure falls, will it rain too much?

1. The gases produced by the full combustion of biogas include carbon dioxide and water.

2. The gases produced by insufficient combustion of biogas include carbon dioxide, water and carbon monoxide.

Biogas: It is a mixture of organic substances under anaerobic conditions through the fermentation of microorganisms. Biogas, as the name suggests, is the gas in the swamp. Since this gas was first found in swamps, it is called biogas.

<>1. In order to ensure that biogas fermentation will not be destroyed, it is necessary to prohibit the addition of various large doses of fermentation inhibitors, especially highly toxic pesticides and various strong fungicides. For the biogas digester that has been damaged due to this reason, all the fermentation raw materials in the digester need to be removed, and then the digester should be rinsed with clean water before it can be re-fed.

2. Too much or too little water in the gas tank is not conducive to the activity of biogas bacteria and the production of biogas. If the water content is too much, the dry matter content in the fermentation broth is small, and the gas production per unit volume is less; If the water content is too small and the fermentation broth is too thick, it is easy to accumulate a large amount of sour fermentation raw materials on the side, and the upper layer of the raw materials for acid fermentation is easy to form a hard shell, which hinders the fermentation of biogas and affects the gas production.

Summary. Dear We are happy to answer for you, the following are the results for your inquiry The reasons why biogas produces gas but cannot be burned are as follows:1

The temperature is not high enough during biogas production: Biogas production requires certain temperature conditions, usually between 25 and 40 degrees Celsius. If the temperature is not high enough, the yield and quality of the biogas will be affected, making it impossible to burn.

2.Biogas contains too many impurities: Biogas contains some impurities, such as hydrogen sulfide, carbon dioxide, etc.

These impurities can affect the combustion performance of the biogas, making it incombustible or incomplete. 3.Insufficient oxygen content in biogas:

The oxygen content in the biogas is necessary for combustion. Warm reminder: check the required items before traveling to avoid omissions; Pay attention to traffic safety and remember to wear a mask I wish you a happy life!

What's the matter if there is a gas point that does not burn.

Dear I am happy to answer for you, the following are the results for your inquiry The reasons why the marsh sail cavity gas produces gas but cannot burn are as follows:1The temperature is not high enough during the biogas generation process

Biogas production requires certain temperature conditions, usually between 25-40 degrees Celsius. If the temperature is not high enough, the yield and quality of the bezoar biogas will be affected, resulting in the inability to burn. 2.

Biogas contains too many impurities: Biogas contains some impurities, such as hydrogen sulfide, carbon dioxide, etc. These impurities can affect the combustion performance of the biogas, making it incombustible or incomplete.

3.Insufficient oxygen content in biogas: The oxygen content in biogas is necessary for combustion.

If there is gas and it is not combustible, what to do if it burns for a while and it will be extinguished.

To ensure that the biogas can be burned, the following measures can be taken:1Control the temperature during the biogas generation process to ensure that it is within the appropriate range.

2.The biogas is purified to remove impurities and improve the purity of the biogas. 3.

Ensure that the oxygen content in the bog collapse disturbance is sufficient, which can be achieved by increasing the aeration volume or adding oxygen. 4.Choose the right combustion equipment to ensure that it is suitable for the combustion characteristics of biogas.

If there is gas and it is not combustible, it will be extinguished after a while, and the treatment method is as follows: 1Check for combustibles:

It is necessary to check whether the combustible material meets the requirements for combustion. It is the poor quality of the fuel or the high water content that causes unstable combustion. If this is the case, you can change the fuel or dry the fuel.

2.Raise Oxygen**: Oxygen is required for combustion, and if there is not enough oxygen**, combustion becomes unstable.

Combustion requires proper temperature and pressure conditions for cherry blossoms. You can adjust the temperature and pressure of the burner to provide better combustion conditions.

Hello dear! Biogas is a renewable energy source produced from the anaerobic fermentation of organic waste, mainly composed of methane and carbon dioxide. Although biogas can be used as fuel, biogas production cannot be burned for the following reasons:

1.The methane content of biogas is unstable, generally between 50% and 70%, and if the methane content is too low, the combustion effect will be affected. 2.

Biogas contains a certain amount of hydrogen sulfide and other sulfides, which can generate sulfur dioxide during combustion, resulting in odors and toxic substances in the exhaust gases produced by combustion. 3.There are also some impurities in biogas, such as water vapor, nitrogen and oxygen, which can affect the combustion effect of biogas.

Therefore, in order for biogas to be completely combusted, it is necessary to carry out appropriate treatment and purification, such as adjusting the amount of methane in Qinghong, removing hydrogen sulfide and other impurities. Only the treated biogas can achieve the desired combustion effect.

Hello, first, the reason for no gas production 1, the fermentation material is not piled up, directly added to the biogas digester. 2. The feeding time is too early and the temperature is low. 3. Pesticide feces and other harmful substances enter the pool.

4. Rat-bite, freeze-cracking, etc., causing gas leakage in pipelines and biogas digesters. 2. The reason for the lack of gas production point 1. Too much feeding at one time, and the neutralization reaction is unbalanced. 2. Only feed but not discharge, resulting in excessive biogas slurry.

3. Add chicken manure, pig manure, human manure and other raw materials, and the carbon-nitrogen ratio and pH are not suitable. 4. No re-inoculum was added. 3. Solution 1: When adding new materials to the pool, it is necessary to pile up for 3-5 days, and the time is after mid-March.

Method: Add square raw materials and add them to the biogas digester in 5 times, with an interval of 1 day each time. 2. The concentration of biogas slurry is generally about 8%, and the concentration is too large, and the neutralization reaction is unbalanced, so that there are too many miscellaneous gases such as hydrogen sulfide and carbon dioxide.

It is required that every time the material is added, how much material is in and how much material is out. 3. Some people mistakenly think that the pH of the biogas digester that is often used will not change, and the correct approach should be to test the pH with test strips frequently, and the pH value is appropriate. If it is acidic, it can be neutralized by adding lime water and plant ash; If it is alkaline, it can be added to wheat straw, corn straw and leaves to neutralize.

4. The carbon-to-nitrogen ratio is 25:1. 5. Some biogas digesters have not been used for a long time, the biogas slurry is aging, the methane activity is weak, and it is difficult to start, so 10% inoculum should be added.

6. When adding new materials, be careful not to add sick animal manure, spray pesticides or leave feces for too long. 7. Before feeding, check whether the pipeline and pool are leaking. Method:

Plug the outlet pipe tightly, blow air into the other end, so that the pressure is expressed to more than 5 air pressures, stop for 10 minutes, see if the pressure gauge drops, and whether the pipeline is leaking; Then use the gas transmission method or the water pressure method to test whether the biogas digester is leaking.
