A biogas generator set is a device that generates electricity by compressing and igniting the purified biogas produced by biomass fermentation in the cylinder of a gas internal combustion engine. Biogas is a combustible gas produced by the fermentation of organic matter such as human and animal manure, crop straw, etc. under suitable temperature and humidity conditions in isolated air (reducing conditions). The main component of biogas is methane, which is an ideal gas fuel. It is colorless and odorless, and when mixed with an appropriate amount of air, it burns immediately. The maximum heat generation per cubic meter of pure methane is 34000 joules, while the heat generation per cubic meter of biogas is approximately 20800-23600 joules. After complete combustion of 1 cubic meter of biogas, it can generate heat equivalent to 0.7 kilograms of smokeless coal. Seal the anaerobic tank, collect biogas, and then equip it with a biogas generator to generate electricity using this combustible gas, which is biogas power generation.
