Biogas overview:

Biogas is a mixed gas generated by the fermentation of organic substances by microorganisms under anaerobic conditions. The more common types of biogas include farm biogas, sewage anaerobic treatment biogas, alcohol plant biogas, starch plant biogas, paper mill biogas, landfill biogas, kitchen waste biogas, etc. These biogas are purchased from farms on the premise of sufficient methane. Biogas generator set can realize biogas power generation. Farm biogas power generation is the most common biogas utilization project in China. It uses the biogas produced by anaerobic fermentation treatment on the engine, and is equipped with a comprehensive power generation device to generate electricity and heat energy. Biogas power generation has the characteristics of efficiency, energy saving, safety and environmental protection. It is a widely distributed and inexpensive distributed energy source.
