Abstract

Abstract: Due to coal jamming, the coal feeder of the Fujian Huadian Kemen Power Generation Corporation Limited had been coerced to shut down repeatedly to clean the coal. It was found by analysis that the reason of the coal feeder blockage is the higher humidity of the asfired coal. The data of the blockage in inlet tube and outlet tube of the coal feeder were compared, and some suggestions on operation were given to ensure the boiler to operate safely and stably.

Key words: electronic weighing coal feeder, blockage, coal mill trip
