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. There are three main areas to be looked at: The burners ...

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.

The BTM is a lowspeed mill that primarily grinds coal by impact and attrition. The VRM is a medium speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed

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% ...
