阳泉矿区矿井煤层气利用发展现状

Development Status of Mine Coalbed Methane Utilization in Yangquan Mining Area

针对阳泉矿区煤层气抽采量较大的特点,阳煤集团积极推动矿井煤层气利用:将煤层气作为民用燃料,用于发电;开发了燃气中央空调和大型燃气锅炉;用于氧化铝焙烧。煤层气的利用提高了煤层气的利用率,节省了燃料煤,减少了煤渣和SO x的排放量。提出了煤层气利用过程中应注意的问题:解决好大型燃气锅炉煤层气燃烧装置与燃气的适配性;发展大工业项目,真正实现以用促抽的良性发展循环等。

According to the features of the large quantity combed methane drainage in Yangquan Mining Area, Yangquan Coal Mining Group actively promoted the utilization of mine coalbed methane.The coalbed methane was applied to the domestic fuel and the power gen- eration.The gas-fired central air conditioning and the large gas-fired boiler were developed.The combed methane was applied to the alumi- na calcination.The utilization of the coalbed methane could improve the utilization rate of the coalbed methane, could save the fuel coal and could reduce the coal cinder and SO~ emission quantity with obvious social and economic benefits.The paper provided the problems to be noted in the utilization process of coalbed methane.The suitability between the combustion device of the large gas-fired boiler and the fuel gas should be well solved.The development of a large industrial project could realize the benign development circulation with the gas utili- zation to promote the gas drainage.
