The main raw material for biogas is biomass. Biogas is a valuable resource with high calorific value and cleanliness. The comprehensive utilization of biogas will help in reducing the greenhouse effect and promoting a virtuous cycle of ecology, which can replace some of the energy such as oil and coal. There are large amounts of biogas resources available for use in farms, food factories, brewing companies, sewage treatment plants, waste treatment plants and other companies.
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, Jichai has devoted itself to the R&D of biogas engines. After years of continuous efforts, 550KW and 1200KW biogas engines have been successively launched, and they can be assembled as generator sets. They are now widely used in China and Southeast Asia.
The use of biogas for power generation is a manifestation of the conversion of biomass to higher-grade energy. The main component of biogas is methane (CH4), which usually accounts for 55% to 65% of the total volume; followed by carbon dioxide, which accounts for the total volume. 30% to 40%; remaining hydrogen sulfide, ammonia, hydrogen, and carbon monoxide gases account for about 5% of the total volume. When the biogas burns completely, it only generates carbon dioxide and water and releases heat energy. It is a clean fuel.
CNPC JICHAI cooperated with WOODWARD Company in the United States, adopting an advanced international gas-fired external mixing method, using advanced electronic control technology and lean-burn control strategy to develop a gas engine with gas and air mixed before turbocharger, which is cost-effective and has good Controllability and reliability. Since the products were put on the market in 2005, they have been sold well both at home and abroad, and have achieved good benefit.
