Coal-bed Methane Generator (600kW/1100kW)
Coal mine methane is also a kind of high-quality energy with high thermal efficiency and less pollution. Coal mine gas is used for power generation, and waste heat recovery equipment is used for recovering the heat of engine exhaust. It can not only reduce greenhouse gas emissions, help develop a recycling economy but also can ease the contradiction between supply and demand of electricity.
Biogas is used for power generation, and waste heat recovery equipment is used for recovering the heat of engine exhaust. Therefore it can realize cogeneration, develop a recycling economy, and the comprehensive utilization efficiency of biogas can reach over 70%. It can not only reduce environmental pollution, benefit the environment, reduce greenhouse gas emissions, but also can ease the contradiction between supply and demand of electricity, reduce production costs, increase the efficiency of enterprises, and increase the competitiveness of enterprises.
Since 2002, CNPC JICHAI has always been devoted to the R&D of biogas engines. After years of efforts, coal-bed methane generator （600kW/1100kW） has been developed which can also be assembled as generator sets to fit different applications.
Since 2005, we have increased investment in R&D of coal mine gas power generation products, focusing on communication and cooperation with relevant scientific research institutes in coal mines, and coal bed methane in China. Advanced control technology and lean combustion technology is adopted to ensure that the gas concentration fluctuates greatly. Through the reasonable matching of the inlet system, the gas turbine unit with gas pressure of 3-15KPa can burn 8%-60% of the methane concentration. Its high safety level and long-lasting reliability guarantee a long service life. Our economical, safe and reliable products have reached the international advanced level.
