Two major parameters which decide the mill capacity and performance are the hardness of coal and the total moisture level in coal. The mill outlet temperature of coalair mixture is maintained between 65 to 90 degree centigrade in the case of low and medium volatile coal. In the case of high volatile coal while the lower limit generally remains as 65 degree centigrade, the upper limit is ...

From the coal yard, the coal is transfer to the mill bunkers through conveyor belt. The bunkers are sized for an effective capacity of twelve (12) hours at BMCR with design coal. Each mill bunker has one hopper, connected to the feeders. Mills operate when the bunker coal gate valves are opened, coal is allowed to flow to the gravimetric feeders.

20. Fineness is an indicator of the quality of the pulverizer action. Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. The mill wear and the power consumption are increased if the 70% ...

Modern coalfired central generating plants make use of a Pulverised Fuel (PF) firing system. This technology is by far the most common for burning coal on a largescale basis and has been around for about 70 years. Boilers up over 1200 MWe have been built, burning something like 400500 tonne per hour of coal.

It can be said that coal as a solid fuel is far more benign as biomass. As a consequence, power stations have started to use modern online measurement and control systems to measure the two phase flow inside PF (pulverised fuel) piping to bring light to the darkness of these problems.
