Coal fired power plants are heavily used due to large and long lasting coal resources compared with oil or natural gas. An important bottleneck in the operation of this particular kind of plants, however, is the coal pulverization process, which gives rise to slow takeup rates and frequent plant shutdowns (Rees Fan, 2003).In typical coal fired power plants, there are 48 coal mills ...

Coal mills are responsible for setting the dustair mixture up which is then burnt in the boiler. The research included the use of one of four mediumspeed ballandrace MKMtype coal mills. The raw coal comes down from the coal tank to the central chute pipe through the feeding screw and gets under the rolling balls being pulverized as a result.

The variables to be controlled are the fuel flow through the mill and particle size distribution at the mill outlet. The differential pressure and motor current of the mill (both depend on coal grindability) are the inputs to the control system. The system has been tested on a pilot plant and on a 1000 MW power station.
