How can agricultural biogas not burn if it has air pressure

The gas quality is not good, which means that the biogas produced has a low methane content and a high carbon dioxide content, so the gas cannot be burned. It is recommended to release all the gas produced, and then collect the gas to see if it can be ignited, if it still can't ignite, you need to adjust the fermentation liquid in the fermentation tank. This is more common during the initial start-up phase of the digester.

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 re-fed, 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. Liquid acidification in the biogas digester, too much one-time feeding, and too high concentration.

If your biogas ignition does not catch fire, release the gas, generally 7 days, the gas smells of rotten eggs, it means that it is running normally, put it a few more times, and it will be fine. If there is no rotten egg smell, the digester is acidified or the raw material is defective. or other issues.

Air pressure is not equal to methane, it is possible that the fermentation is not successful, if the seal is not good, it becomes aerobic, and there is only CO2 in the gas, so check the air tightness and methane content, but be careful of the danger, hehe.

Is there a gas point that does not burn? The reasons are: 1. Too much feeding, the raw materials, methanogens can not be completely decomposed, resulting in the accumulation of organic acids, inhibiting the growth of methanogens, acidification of biogas fermentation broth, and high carbon dioxide content of the gas.

2. The biogas digester enters harmful substances, such as disinfectants and fungicides, various highly toxic pesticides, etc., which inhibits the growth of methanobacteria. In the case of the above situation, it is necessary to analyze and find out the cause, if it is too much feeding, it is necessary to stop the feeding, then take out part of the feed liquid, and then add 10 to the biogas bacteria, which can generally recover quickly. If harmful biocidal substances are introduced, most of the feed must be removed, and then a new biogas culture must be introduced and new fermentation raw materials must be added.

Otherwise, it will be difficult to resume gas production. The acidification phenomenon of the biogas digester occurs (the gas production point is not combustible), some people advocate the use of lime water to adjust the pH, although the method has a certain effect, but if the biogas bacteria are not added, the gas production recovery time is longer, and the best way is to add enough old biogas digester slag liquid. If the damper can be opened half of the biogas stove when it is in use, the flame does not burn away from the stove, and the material can be properly fed, if there is a de-fire (the flame leaves the stove surface to burn or is extinguished when the cooker is removed), the feed should be reduced or stopped.

The methane content in the biogas does not exceed 35%.

If there is no problem with your stove, (1) the methane content is low, 1: the temperature is too low, add water to cool down: the raw materials are piled up to heat first, and the water that has been exposed to the sun is added.

2: The fermentation broth becomes sour: after checking and confirming with pH test paper, it is determined to become sour, and neutralized with lime water or plant ash.

3: No inoculum: Add inoculum.

Such as activated sludge - ditch bottom sludge or old biogas digester fermentation raw materials. 4: The fermentation raw materials in the digester contain toxic substances

Refueling. 2) There is too much miscellaneous gas, if it can't be lit, you have to let out all the miscellaneous gas until it can be ignited.

3) There may be two reasons for gas production, but it cannot be burned: one is that the pH is not appropriate, which is generally acidic, and a small amount of lime water can be added to the biogas digester, and a small amount of ammonia can also be added; The second is that there is a lot of raw material input, resulting in the production of carbon dioxide. As long as an appropriate amount of sludge and the foot of the old manure kiln are added to the tank, biogas can be produced soon.

1. If the newly built biogas just produces gas, it is exhaust gas, which is not combustible. It needs to be discharged for a period of time (to the outdoors), so pay attention to safety. 2. If it is a normal use of biogas, it suddenly does not burn, more than 90% of it is a problem of materials, see if there are disinfectants, laundry detergents and other chemicals in the materials that have been imported recently; 3. It may also be the cause of the biogas stove, try to change the stove, but this possibility is relatively low.

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: We are happy to answer for you. The gas production of your biogas digester means that the pond is well repaired and successful, and the gas point is not flammable because the methane content of the gas produced by the new pond is low, don't worry, you can:

1. Add a large amount of sludge from the old biogas slurry or old manure tank, which will ignite soon; 2. If you don't want to add materials, you don't stop gasing, and at the same time close the intake valve of the small stove, and it will be ignited soon. Tips: The biogas digester is strictly forbidden to enter garlic, tobacco, chili, washing powder, soapy water, batteries, especially pesticides, insecticidal water, etc., these substances will destroy the reproduction of anaerobic bacteria, resulting in little or no gas production in the pool, so be careful.

Hope it helps, thank you.

Summary. There is a gas point that does not burn because the gas methane content produced in the new pool is low, don't worry, you can:

Add a large amount of sludge from the old biogas slurry or old manure tank, and it will ignite soon;

If you don't want to refill, you don't stop gasing, and at the same time close the intake valve of the small stove, and it will soon ignite.

Garlic, tobacco, chili peppers, washing powder, soapy water, batteries, especially pesticides, insecticidal water, etc., are strictly prohibited from entering the biogas digester, which will destroy the reproduction of anaerobic bacteria, resulting in less or no gas production in the pool, so be careful.

Why don't you ignite a fire if there is gas in biogas.

I have been in the pool for many years, and this time after adding pig manure, I suddenly couldn't ignite the fire.

This means that your biogas slurry is not pure, you extract a small part of the biogas slurry, and then add another gas biogas slurry, this is called inoculation, and you can light the fire in 3-5 days, but you have to continue to deflate during this period. It is impossible to light a fire all at once.

It was very easy to use a few days ago, and the gas production was not too much, because there was not much material, so it did not catch fire after adding the material this time, but this time there was more gas production.

It is recommended that you find a professional to consult and solve this problem for you.

The advice given to you by this platform may affect your judgment.

Aren't you just a transfer of personnel, there is almost no biogas around us, and a lot of it has been built in the past few years, but it can't be used, just I can use it.

I'm sorry, but this one of ours is categorized.

Summary. What should I do if the rural biogas can't ignite the fire?

The new biogas digester is fed with no or little strain, and the gas produced has a high carbon dioxide content (the gas has a sour smell), which not only does not ignite, but also is extinguished when the open flame is close. In this case, part of the feed liquid must be removed and then 15-20 quintals of old biogas digester residue liquid must be added.

The new biogas digester has less fermentation raw materials, and the fermentation tank leaves a large space, and the newly added fermentation raw materials have some residual air, so the purity of the gas produced is not high. In this case, after a few days, the exhaust gas is repeatedly put several times, and then some raw materials are added.

2.The new biogas digester has less fermentation raw materials, and the fermentation tank leaves a large space, and the newly added fermentation raw materials have some residual air, so the purity of the gas produced is not high. This situation is generally after a few days, the anti-source spike re-release state, such as several exhaust gases, and then add some raw materials, too.

The reply was too slow.
