民用燃煤大气污染物控排技术对策

Countermeasure of air pollutant controlled pollutation for civilian coal

民用燃煤在我国煤炭消费中所占比例较大,民用燃煤粗放、低效的利用方式导致大量气态污染物的排放,造成环境污染。通过文献调研和查阅相关数据介绍了我国目前民用燃煤使用状况及大气污染物排放现状,通过数据调研可知传统的民用燃煤利用方式的主要气态污染物(颗粒物、SO_2、NO_x、VOCs)的排放因子均高于工业污染源的排放因子,因此减少民用燃煤主要大气污染物排放的有效途径是使用洁净煤替代原煤散烧及使用高效节能炉具。

Civilian coal occupies a large proportion of coal consumption in China,and the extensive and inefficient use of civilian coal leads to the discharge of a large number of gaseous pollutants,resulting in environmental pollution.Current situations of civil coal combustion and air pollutant discharge in China were introduced,through a literature survey and analyses of relevant data.According to the data investigation,the emission factors of main gas pollutants from civil coal combustion（ particulate matter,SO2,NOx ,VOCs） are higher than those of the industrial pollution source.Therefore,the effective ways to reduce main atmospheric pollutant emissions of civil coal include the use of clean coal as an alternative and the application of efficient energy-saving stove.
