摘　　要：针对四角切圆燃烧锅炉很少配备双进双出钢球磨煤机为基础的直吹式制粉系统的情况 ,结合美国 Svedala公司生产的双进双出钢球磨煤机及其系统 ,介绍了磨煤机模拟量控制 ,并重点阐述了磨煤机顺序启停控制逻辑 。Aimed at the status that corner tangential firing boiler is seldom equipped with direct fired circulating system based on double input and double output steel ball coal mill, such system made by American Svedala Company is introduced. The sequence control logic of start stop applied to the mill is presented based on introducing the control of analog quantity. It is generalized the problems of mill in commissioning process and its settlement.
