Pulverizers 101: Part 3

bituminous coal with 10% total moisture as an example. The coal is dry to the touch and the 10% moisture is inherent moisture - moisture that will not be removed by air-drying or by being stored on a sunny summer day on the coal pile. Inherent moisture is basically liquid phase water that is bound within the coal. It will not be released until the coal is pulverized and/or exposed to high ...

Boiler Performance and Mill Outlet Temperature -

Two major parameters which decide the mill capacity and performance are the hardness of coal and the total moisture level in coal. The mill outlet temperature of coal-air mixture is maintained between 65 to 90 degree centigrade in the case of low and medium volatile coal. In the case of high volatile coal while the lower limit generally remains as 65 degree centigrade, the upper limit is ...
