摘　　要：燃料燃烧过程是大气中可吸入颗粒物的主要来源之一。从燃煤过程中颗粒物的来源及一次颗粒物的生成途径进行分析,相应提出了控制燃煤过程可吸入颗粒物的燃烧前控制、燃烧中控制和燃烧后控制。燃烧前控制包括了煤种选择和煤粒加工;燃烧中控制措施有调整燃烧工况和使用添加剂;燃烧后控制是通过使细颗粒物凝并、团聚为较大颗粒物后再利用除尘设备加以脱除。Coal combustion is one of main sources of inhalable particulate matter（PM_10）.The resource of PM and the formation pathways of primary PM during coal combustion were analyzed firstly,accordingly,the control measures of PM_10 generated by coal combustion were put forward,which were controlbefore combustion,control during combustion and control after combustion.Control before combustion include coal type selection andcoal milling.Control during combustion represent combustion conditions adjustment and additive.Control after combustion is coagulating and aggregating the fine particles to bigger particles via some methods and then removing the PM by air pollutants control devices（APCDs）.
