Experience has shown that coal–biomass blends can be pulverized in atritta mills, but ball mills, bowl mills, and the large MPS (vertical spindle, tire-based) mills are not successful at pulverizing coal–biomass blends [12]. For coal–coal blends, the pulverizer is often the first area where a load limit is encountered. This is ...
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 ...
