Biogas generator set using biogas produced by industrial, agricultural or urban life organic waste (such as liquid lees, livestock manure, municipal waste and sewage, etc.) anaerobic fermentation, through combustion in engine driven generator work, gas generator set waste heat can be used for heating, bathing or biogas production.  300 series biogas generator set is optimized designed especially for the characteristics such as high sulfur content, high carbon dioxide content of biogas, has good stability and strong adaptability, and has great influence in the field of biogas power generation. Because the methane is high grade, clean and green energy, production cost is lower than conventional energy, so the market prospect is good.
