COAL BASED THERMAL POWER PLANTS: COAL MILLS

13-12-2011  Ball tube mills are either pressurized or suction type. In the pressurized type, the hot primary air is used for drying the coal and to transport the milled coal to the furnace. In this type, leakage in the mill area is high.In the suction type, the exhauster is used for lifting the milled coal from the pulverizer to the furnace through a cyclone.

Coal mill pulverizer in thermal power plants

17-11-2012  10.Bowl Mill Bowl mills are employed to pulverize the pre-crushed raw coal to the required fineness before it is admitted into the boiler furnace for combustion. The mill output can be easily varied, as per the turndown ratio from its minimum to maximum load. Crushed raw coal at a controlled rate is fed into the revolving bowl of the Bowl Mill. Centrifugal force feeds the coal uniformly over the

Types of Boiler Coal Pulverizers - Bright Hub Engineering

29-01-2010  Thermal power plants use different types of coal pulverizers. The method used is attrition, impact, or a combination of both. This article explains the characteristics of the three main types- attrition, impact and attrition, and impact or hammer. Selection of the type of pulverizer depends on the grindability of the coal, the capital costs and maintenance costs, and considerations for licensing.
