Effects of Mill Performance on Unburnt Carbon in Coal
Pulverized coal were sampled isokinetically from the PC pipes The results indicate that there is a significant mal distribution of coal mass flow in the PC pipes The particulate size was also coarse As a result the heat release from the combustion of coal occurred higher up in the boiler leading to a flue gas exit temperature.
