Understanding how biogas is produced is helpful for better use of biogas generating units. Specific content jichai introduction!

沼氣是一種可燃氣體，由于這種氣體先是在沼澤中發現的，所以稱為沼氣。

Biogas is a kind of combustible gas, because this gas was first found in the swamp, so it is called biogas.

那么 ，沼氣是怎樣產生的？

So, how is biogas produced?

沼氣是有機物在隔絕空氣和某溫度、濕度、酸堿度等的條件下，經過沼氣細菌的作用產生的一種可燃氣體。

Biogas is a kind of combustible gas produced by biogas bacteria under the condition of isolation of air, temperature, humidity, pH, etc.

沼氣含有哪些成分？

What are the components of biogas?

沼氣是一種混合氣體，主要成分是甲烷、其余為二氧化碳、氧氣、氮氣和硫化氫。其中甲烷含量約為55%-70%，二氧化碳含量約為30%-45%。

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

沼氣的物理、化學性質怎樣？

What are the physical and chemical properties of biogas?

沼氣的主要成分是甲烷。甲烷是無色、無臭的氣體，分子式CH4，分子量為16.04，在一個大氣壓下甲烷對空氣的相對密度為05548，沼氣約為0.94。

Methane is the main component of biogas. Methane is colorless, odorless gas, molecular formula CH4, molecular weight is 16.04, in an atmospheric pressure, the relative density of methane to air is 05548, biogas is about 0.94.

沼氣發動機廢氣的余熱利用方法？

Waste heat utilization method of biogas engine exhaust gas?

1）發動機廢氣的余熱→通過廢熱鍋爐產生蒸汽→加熱消化器

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

2）發動機廢氣的余熱→通過換熱器產生熱水→加熱消化器

2) Waste heat of engine exhaust gas → hot water generated by heat exchanger → digester heated

3）發動機廢氣的余熱→通過廢氣吸收式冷熱水熱水器→用于空調系統

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

沼氣燃燒發電是隨著大型沼氣池建設和沼氣綜合利用發展而出現的一項沼氣利用技術，它將厭氧發酵處理產生的沼氣用于發動機上，并裝有綜合發電裝置，以產生電能和熱能。當然除了沼氣發電機組，還有柴油發電機組、汽油發電機組、秸稈氣發電機組等類型。用戶在選擇發電機組的時候要根據工作需要選擇適合的機組！

Biogas combustion power generation is a biogas utilization technology with the development of large-scale biogas digester construction and comprehensive utilization of biogas. It uses biogas produced by anaerobic fermentation for engine, and is equipped with comprehensive power generation device to generate electric energy and heat energy. Of course, in addition to biogas generator set, there are diesel generator set, gasoline generator set, straw gas generator set and other types. When users choose the generator set, they should choose the right one according to their work needs!
