摘　　要：瓦斯是与煤炭共同伴生的优质洁净能源,同时也是一种温室气体,其危害是CO_(2)的21倍,国际清洁能源组织把瓦斯作为主要温室气体之一,要求各国尽可能降低煤矿向大气排放瓦斯。在实际生产中,有些已建成投产低浓度瓦斯发电站,在运行中,出现了低浓度瓦斯因浓度过低,发电机组无法运行发电;而采用高浓度瓦斯发电,空燃比调节受限,存在机组启动困难等问题,为此研究采取高低浓度瓦斯混掺发电技术,既提高瓦斯利用率,又减少了瓦斯排放,增加了发电量,具有良好的经济和社会效益。Gas is a high-quality clean energy associated with coal,and it is also a kind of greenhouse gas.Its harm is 21 times of CO_(2).The international clean energy organization regards gas as one of the main greenhouse gases,and requires all countries to reduce the gas emission from coal mines to the atmosphere as much as possible.In actual production,some low concentration gas power stations have been built and put into operation,Because of the low concentration of low concentration gas,the generator set can not run to generate electricity;while using high concentration gas to generate electricity,the air-fuel ratio regulation is limited,and the unit is difficult to start.Therefore,the research adopts the high and low concentration gas mixing power generation technology,which not only improves the gas utilization rate,but also reduces the gas emission,and increases the power generation.It has good economic and social benefits.
