The raw coal is then fed into the pulverizer along with air heated to about 330 C 650 F from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows the usable fine coal powder out to be used as fuel. The powdered coal from the pulverizer is directly blown to a burner in the boiler.

Aug 13, 2009 Coal parameters affecting pulverizer output. While selecting a pulverizer, the coal characteristics play an important role. The Hardgrove index, total moisture, input coal size, output fineness, and mill wear have direct impact on the mill output. The Hardgrove index of coal tells us about the ease with which it can be pulverized.

Coal processingsize reduction consists of crushing and grindingpulverizing. Coal is typically received at the power plant crushed to 2 inches 0 5 cm 0. It then undergoes additional crushing and grinding grinding for pulverized coal-fired units.
pacted on a grid section by swing hammers, reducing the coal to a nominal 14 size. Drying of the coal also occurs in this section. After the coal passes through the grid section, it enters the two-stage pulverizing sec- tion. This section further reduces the coal size by attrition and by impact of coal on the moving and stationary parts.
