Get Price. Abstract. In the early 1960's, Foster Wheeler introduced the first mill, a planetary roll pulverizer which proved to have many outstanding operational charcteristics. Among these were low power consumption, the ability to handle extremes of coal moisture, freedom from fires, and equality of coal distribution to its connected burners.

Fote's coal mill has been improved. The drying bin of the Fote coal mill has been shortened from the original 3m to 2.1m, and the grinding silo is extended by 0.9m, so that the length ratio between the drying bin and the grinding bin can reach 1:2.81. Such a change can grind coal pieces more fully, and can also grind inferior coal finer in

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.
