Why Pulverized Coal is Used in a Power Plant

Modern boilers powder the coal to a very fine dust so that while burning, it is almost like a fluid stream. The size of the coal particles is in the range of 75 microns. This means every particle comes into contact with the air. The loss due to unburned carbon is only in the range of 0.5 % or less making the boilers very efficient.

Coal Pulverization System: Explosion Prevention and …

Raw coal is conveyed from the storehouse by a belt conveyer. Then it is lifted to the entrance level of a vertical cylindrical mill by a bucket elevator, and an electromagnet is used to remove iron objects from the raw coal. The raw coal is pulverized in the vertical cylindrical mill, and the pulverized coal is lifted to a powder separator by

Standard Test Method for Sampling and Fineness Test of Pulverized Coal

1.1 This test method covers the determination of the fineness by sieve analysis of coal sampled from a dry pulverizing operation. It is not applicable to products of wet milling or to fines that have clustered into an agglomerated mass. 1.2 The values stated in SI units are to be regarded as standard.
