摘要
锅炉给粉机电机原采用滑差调速，存在故障率高、维修量大且调速性能差等问题。
There were higher failure rate, large maintenance and poor char- acteristics of speed governing due to using slip speed governing of motors for feed- ers of coal for boilers. The above problems are well solved after using frequency converters for speed governing.
