辽宁中部地区煤矿瓦斯发电机组尾气污染特征分析

发电是煤矿瓦斯被有效资源化的重要手段,既可以有效地解决煤矿瓦斯事故,改善煤矿安全生产条件,又有利于增加洁净能源供应,减少温室气体排放。通过对6个低浓度煤矿瓦斯发电机组的尾气进行主要污染物和烟气参数的监测,掌握污染物浓度水平及针对《火电厂大气污染物排放标准》(GB 13223—2011)、《车用压燃式、气体燃料点燃式发动机与汽车排气污染物排放限值及测量方法(中国Ⅲ、Ⅳ、Ⅴ阶段)》(GB 17691—2005)两个标准的达标情况,进而对辽宁中部地区煤矿瓦斯发电机组尾气的污染特征进行初步分析。

Coal mine gas power generation is an important means of effective resource utilization of coal mine gas,which can effectively solve the coal mine gas accident,improve the conditions of coal mine safety production,increase the supply of clean energy and reduce the emissions of greenhouse gas. Through the monitoring of the main pollutants and flue gas parameters of the six low-concentration coal mine gas generators,the pollutant concentration level and the compliance condition of Emission standard of air pollutants in thermal power plants(GB 13223-2011) and Vehicle Compression Ignition,Gas Fuel Ignition Engine and Automobile Exhaust Pollutant Emission Limits and Measurement Methods(China Ⅲ,Ⅳ,Ⅴ)(GB 17691-2005)were grasped,and the pollution characteristics of the tail gas in the coal mine gas generators in central Liaoning were analyzed.
