Abstract

Abstract: The features of the 600MW supercritical Wshape flame coalfired power unit of Huadian Sichuan Gongxian Power Generation Company Limited were analyzed. The object properties and control difficult points of the supercritical unit were introduced; the tasks, the structure and the control strategy of the water feeding adjustment system were described. Based the original design, the adjustment system was improved and optimized; and favorable effects were obtained in practical application.

Key words: once-through boiler, W-shape flame boiler, supercritical unit, feed water control, fuel/water ratio control
