摘　　要：我国煤烟污染十分严重。燃煤排放的PM10和PM2.5表面富集了大量的有毒痕量元素,进入大气后,对环境的危害极大。本文在一维炉中对不同煤种分别在650℃,850℃,950℃下燃烧PM的排放进行实验研究,发现PM10和PM2.5的排放量随温度升高有增加的趋势;随煤种含S量的增加,其排放量也增加;随着煤灰分的增加,PM10和PM2.5的排放量也有增大的趋势,煤中矿物质的种类和形态对其排放有明显的控制作用。Coal combustion polluted environment seriously in our country. Particulate matter emission during coal combustion would enrich some toxic trace elements and would do harm to environment when they emitted into atmosphere. This study focus on the emissions of PM during coals combustion in one dimensional furnace on different temperature, discussed the influence of temperature, S content, and ash content on the emission of PM10 and PM2.5 results indicated that the emissions of PM increase with the increase of temperature; also increase with the higher content of S and the higher content of ash content in coals, the mineral species have most impact on the emissions.
