Design and application of automatic startup and shutdown function for coal pulverizing system of 600MW supercritical unit

Abstract

Abstract: Abstract:Taking the coal pulverizing system of the 600MW supercritical unit as example, the control strategy of automatic startup and shutdown of the coal pulverizing system was introduced. The function groups of mill heat soaking, mill startup and mill shutdown were designed. The technical difficulties of each function group were analyzed. The concrete control processes of each function group were given. The automatic startup and shutdown control of the coal pulverizing system was realized, and the effectiveness and the rationality of the control strategy were verified by the operation result of the system.

Key words: Keywords:coal pulverizing system, automatic control, automatic startup and shutdown system, function group
