Dipak K. Sarkar, in Thermal Power Plant, 2015. 13.2.17 Loss of coal feeder. Loss of a coal feeder causes raw coal feed to associated puverizer to shut off. Since in a direct firing system, fuel is fired according to the requirement of the steam demand and reserve fuel in a pulverizer is very limited, a loss of feed will cause unbalance in operating pulverizer/s, thereby impairing the furnace ...
Each mill pulverizer is responsible for about 130 megawatts of power. When the coal quality is good, the unit can run at full capacity on five pulverizers. Therefore, in the event of a failure, the impact on production is minimal assuming a second pulverizer does not fail. The plant maintains two gearboxes as spares because this dual failure ...

Coal is first fed from silos at the plant to coal mill pulverizers, which grind the coal into a fine powder. A fan blends and forces a primary flow of mixed ambient "cold" air and pre-heated "hot" air into the coal mill. This air is mixed with the coal powder creating a combustion air .
The coal-pulverizer is an important unit, which pre-processes coal-fuel fed to the boiler in coal-based thermal power plants. It is extremely important to comprehend the operational behavior of the coal pulverizer unit for good performance of the boiler and overall coal power-plant.
