摘要

平煤集团坑口电厂 1号炉给粉机调速系统由原来的滑差控制改为变频控制

取得了良好的效果 :(1)调速性能良好

给粉系统安全稳定 ;(2 )节能显著 ;(3)运行水平提高

劳动强度降低

Abstract

The speedregulating system of pulverizedcoal feeder to boiler No.1 in minemouth power plant of Pingmei Group has been retrofitted from original slip control to variable frequency control

obtaining good results:(1)speedregulating performance to be upgraded

pulverizedcoal feeding system being safe and stable in operation; (2)the amount of pulverizedcoal feeding to the boiler to be controlled by variable frequency mode

reducing coal consumpsion; (3)energysaving to be obvious; (4)operatin level to be enhanced

lowering labour intensity.
