中文摘要：
实验室条件下,以沉降炉作为燃烧设备研究煤粉细度、燃烧时间、燃烧温度、添加吸附剂等不同条件对煤粉燃烧后生成的一次颗粒物中PM10、PM2.5、PM1 （统称为“可吸入颗粒物”）排放特性的影响.煤粉在不同条件下燃烧后,用8级Andersen粒子撞击器分离并收集燃烧后的颗粒物,比较和分析了不同条件对煤粉燃烧后PM10、PM2.5、PM1排放的影响.结果表明：煤粉越细、燃烧时间越长、燃烧温度越高,生成的PM10、PM2.5、PM1的量均越大;煤粉中添加CaO后,对颗粒物的凝并和团聚起到了一定的作用,降低了可吸入颗粒物的排放量.
英文摘要：
Experiments were carried out on laboratory-scale drop tube furnace to study the coal fineness, burning time, burning temperature and adsorbent effecting on the PM10, PM2.5, PM1 emission features after the combustion of pulverized coal. An 8-stage Andersen particle sizing impactor was employed to separate and collect the primary particulate matter after coal combustion at different conditions, and the emission features of PM10, PM2.5, PM1 were compared and analyzed. The results showed that the finer the coal size was, the more amounts of PM10, PM2.5, PM1 were emitted. The longer burning time and the higher burning temperature had the same results. The adsorbent used in the coal combustion effected on the coalescence and aggregation of PM10, PM2.5, PM1 to some degree, resulted to the debasement of PM emission.
