To meet the fuel-rich requirements for coal gasification, the CCS uses an “indirect-coal-firing” scheme. Raw coal from the existing bunker is fed to a pulverizer by a metering feeder and milled and dried with a quantity of hot sweep gas extracted from the boiler exhaust. The sweep gas and powdered coal are then separated in a bag house. The dry.
In a coal-fired power plant, the coal pulverizer is critical for fuel processing. It is important to operate the pulverizer properly following the OEM specified procedure and NFPA code requirements. The increased use of highly volatile sub-bituminous coal such as Powder River Basin (PRB) coal.

Combustion of coal particles beneath the grinding zone is not a seri-ous problem, as long as the mill is in operation. But if a mill trips or a boiler has a main fuel trip, then fires in the pyrites zone (beneath the grinding zone) are the most common cause of pulverizer “puffs,” in our experience. A fire beneath the grinding zone provides the.
