Abstract: The problem of ash and slag with high water content has existed since the No.1 boiler of The Mine Mouth Power Plant of Pingdingshan Coal Group Corporation Limited was put in operation, it was occurred quite often that the chainbucket conveyor and bucket elevator were stuck and plugged by ash. After analysis, the following reformation methods were proposed: parching the ash and slag to remove the water, then transmitting them to the chainbucket conveyor and bucket elevator through a conveyor, and finally entering into the storage silo. The application of these reformation methods has decreased intensity of work and gotten obviously economical effects.

Key words: ash and slag, water content ratio, parch, bucket chain conveyor, bucket elevator
