针对气化工序灰水系统高压灰水泵设计裕量偏大、运行效率低、电耗高、回流管线振动大的问题，将高压灰水泵改为变频调节。改造后，在2台气化炉运行的工况下，回流减压阀全关，电机电流由改造前的140 mA左右降至95 mA左右，节能效果非常明显，回流管线振动大的问题也随之解决。

In connection with problems of high pressure ash water pump of ash water system in gasification process, such as large design margin, low operation efficiency, high electricity consumption, and excessive vibration of reflux lines, the adjustment of high pressure ash water pump is changed to frequency conversion adjustment.After renovation, in operation conditions of 2 gasifiers, pressure reducing valves are all closed, motor current is reduced from about 140 mA before renovation to about 95 mA, having significant energy saving effect, and the problem of heavy vibration of reflux lines is solved.
