PDF Analysis of the Coal Milling Operations to the Boiler Parameters

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.

Advances in pulverised fuel technology: understanding coal comminution ...

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.
