Coal Pulverizers an overview ScienceDirect Topics
网页In the same way with conventional coal firing boiler, raw coal fed from coal bunker is dried and grinded in the coal pulverizer. However, in the case of IGCC, part of the flue gas from the GT is extracted from the HRSG as the drying gas at the pulverizer. Pulverized and dried coal is fed to the gasifier by a pulverized coal feeding system.
