中国煤层气发电技术发展和应用现状

煤层气发电是煤层气利用的重要途径之一,以中国"十一五"期间煤层气发电的进展为背景,研究并分析了燃气发电设备在煤层气发电方面应用的优缺点以及适用范围,重点对基于内燃机的联合循环和热电(冷)联产系统方案进行分析,指出内燃机发电机组在煤层气发电方面的应用较为广泛,大规模煤层气发电项目大多采用联合循环热电发电形式,较小规模则采用热电冷联产方案,并结合具体案例进行经济分析。最后,对煤层气发电项目发展方向进行了展望。 Electricity generation is one of the most important ways to utilize coalmine methane(CBM) resources.Study and analyze the advantages and disadvantages of gas generating equipments in CBM electricity generation with the background of CBM electricity generation during the eleventh five years plan of China.Emphatically analyze combined cycle system and the co-production system of heat,electricity and cold based internal-combustion engine.The results show that internal-combustion engine power units are widely applied in CBM electricity generation,and the combined cycle system is suitable for lager-scale CBM programs while the cool,heat and electricity co-production system is suitable for small-scale CBM programs.Economic analysis of the systems has been conducted according to the specific case and the development direction of coalmine methane power generation projects has been discussed
