What is Thermal Power Plant? Working and Operation
Storage of coal is primarily a matter of protection against coal strikes, failure of transportation system and general coal shortages. From the coal storage plant, coal is delivered to the coal handling plant where it is pulverized in order to increase its surface exposure, thus promoting rapid combustion without using large quantity of excess air.

THERMAL POWER PLANTS: COAL PULVERISING IN BOILERS
Pulverized coal is the most efficient way of using coal in a steam generator. The coal is ground so that about 70 % will pass through 200 mesh ( mm) and 99 % will pass through 50 mesh ( mm). A pulverized coal boiler can be easily adapted for other fuels like gas if required later without much difficulty. However, during the design ...
