【Abstract】 This paper introduces the main problems revealed in commissioning stage in the dry ash handling system of Hengshui Power Plant. Following systems were improved and some deficiencies of equipment were corrected: cooling water system for air compressors,over-temperature of compressed air drier and its inlet air,pressure reducing valve in gasify heating system,gas inlet system for intermediate ash silo heating,matching between scraper conveyer and air locker,feeders,inlet tee-joint of gasifying ejector and gas discharge piping,etc. For the remaining problems,some proposals are suggested after analysis.更多还原
