To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.

PULVERIZING PLANT / COAL MILL: In modern thermal power generation plants in order to achieve maximum burning efficiency coal is pulverized or ground in order to mix it with the hot air and then feeding to furnace in a stream of hot air. This helps increasing the surface area of the coal to action of oxygen and consequently helping combustion.

COAL BASED THERMAL POWER PLANTS: COAL MILLS FOR THERMAL STATIONS COAL BASED THERMAL POWER PLANTS Coal Pulverizing in Boilers Pulverizing coal for a boiler is very important factor in overall cycle efficiency. There are many types of pulverizers available, but proper selection will ensure consistent boiler and cycle efficiency.
Details 
The main Function of the Pulveriser in thermal power plant is to crush/grinding the raw coal coming from coal handling system through coal feeder into a pre-determined size in order to increase the surface area of the coal. If the coal is not pulverised, the coal might not burn completely, thus resulting in wastage of fuel.

between 0.80.9 kg/kWh, seven plants use between 0.9- 1.0 kg/kWh, and at three plants - coal usage exceeds 1.0 kg/kWh. Hence the efficiency of the plants and the coal usage per unit of electricity generation also differ at each plant. There is a need to modernize India's thermal power plants and reduce the coal usage per unit of
