解沼气是怎么产生的,助于更好的使用沼气发电机组。具体内容济柴环能燃气介绍！

Understanding how biogas is produced helps to better use biogas generator sets. Specific content: introduction to jichai Huanneng gas!

沼气是一种可燃气体，由于这种气体先是在沼泽中发现的，所以称为沼气。

Biogas is a combustible gas, which was first found in the swamp, so it is called biogas.

那么，沼气是怎样产生的？

So, how is biogas produced?

沼气是有机物在隔绝空气和某温度、湿度、酸碱度等的条件下，经过沼气细菌的作用产生的一种可燃气体。

Biogas is a combustible gas produced by organic matter under the condition of isolating air and a certain temperature, humidity and pH through the action of biogas bacteria.

沼气含有哪些成分？

What ingredients does biogas contain?

沼气是一种混合气体，主要成分是甲烷、其余为二氧化碳、氧气、氮气和硫化氢。其中甲烷含量约为55%-70%，二氧化碳含量约为30%-45%。

Biogas is a mixed gas, the main component is methane, and the rest is carbon dioxide, oxygen, nitrogen and hydrogen sulfide. The content of methane is about 55% - 70%, and the content of carbon dioxide is about 30% - 45%.

沼气的物理、化学性质怎样？

What are the physical and chemical properties of biogas?

沼气的主要成分是甲烷。甲烷是无色、无臭的气体，分子式CH4，分子量为16.04，在一个大气压下甲烷对空气的相对密度为05548，沼气约为0.94。

The main component of biogas is methane. Methane is a colorless and odorless gas with molecular formula CH4 and molecular weight of 16.04. Under one atmospheric pressure, the relative density of methane to air is 05548 and biogas is about 0.94.

沼气发动机废气的余热利用方法？

Waste heat utilization method of biogas engine exhaust gas?

1）发动机废气的余热→通过废热锅炉产生蒸汽→加热消化器

1) Waste heat of engine exhaust gas → steam generated through waste heat boiler → heating digester

2）发动机废气的余热→通过换热器产生热水→加热消化器

2) Waste heat of engine exhaust gas → hot water generated through heat exchanger → heating digester

3）发动机废气的余热→通过废气吸收式冷热水热水器→用于空调系统

3) Waste heat of engine exhaust gas → through exhaust gas absorption cold water heater → for air conditioning system

沼气发电机组是随着大型沼气池建设和沼气综合利用发展而出现的一项沼气利用技术，它将厌氧发酵处理产生的沼气用于发动机上，并装有综合发电装置，以产生电能和热能。

Biogas generator set is a biogas utilization technology with the construction of large biogas digesters and the development of comprehensive utilization of biogas. It uses the biogas produced by anaerobic fermentation treatment on the engine and is equipped with comprehensive power generation device to generate electric energy and heat energy.

当然除了沼气发电机组，还有柴油发电机组、汽油发电机组、秸秆气发电机组等类型。用户在选择发电机组的时候要根据工作需要选择适合的机组！

Of course, in addition to biogas generator set, there are diesel generator set, gasoline generator set, straw gas generator set and other types. When selecting the generator set, the user should select the appropriate unit according to the work needs!
