摘　　要：通过对元宝山电厂 3号锅炉制粉系统出力不足的原因分析 ,提出了在锅炉四角切圆燃烧方式中 ,将风扇磨制粉系统中采用的每台风扇磨出口一次风管道与一个角的燃烧器相连接的布置方式 ,借鉴到中速磨制粉系统中的一个设想 ,并对该改造方案的可行性进行了充分的论证。若将元宝山电厂 3号炉的一次风管道布置方式进行此项改造 ,可降低制粉系统阻力 ,达到提高制粉系统出力 。Through the cause analysis on the insufficient output of No 3 boiler coal-preparation system in Yuanbaoshan Power Plant,extracting experience from the medium-speed pulverizer system,a deployment for the four-corner tangential circle combustion mode of boiler is put forward,in which the primary draft pipe of the outlet of each fan mill in the coal-preparation system will be connected to the burner of a corner;and the feasibility of this reform scheme has been fully expounded and proved. If this deployment reform would be implemented,the resistance of coal-preparation system can be reduced,and the purpose of raising the coal-preparation output and reducing the electric consumption could be achieved.
