双进双出钢球磨煤机的控制策略优化

The Optimization of the Control Strategy of Double Inlet and Double Outlet Ball Coal Mill

本文介绍了双进双出钢球磨煤机的工作特点,并对原双进双出磨煤机的热、冷一次风门逻辑的不合理之处进行了详细分析,提出了修改后双进双出磨煤机的热、冷一次风门逻辑,实际运行效果表明该控制逻辑稳定可靠,保证了磨煤机分离器出口温度自动控制的长期投入。

First,this article introduces the basic trait of the double inlet and double outlet ball coal mill,then analysises in detail the unreasonable logic of the hot and cool air flippers of the double inlet and double outlet ball coal mill,at last the modified logic of the hot and cool air flippers of the double inlet and double outlet ball coal mill is put forward.The actual operation result indicate stable and reliable of the control logic,which can make sure the output temperature control system of the separator in long-term operation for the double inlet and double outlet ball coal mill.
