Coal Grinding Operation Objectives and KPIs: Highly energy intensive unit operation of coal grinding is intended to provide a fine coal as a fuel for calcination and clinkerization. Coal grinding operation is monitored for following parameters to ensure objectivity and economy of operation.
Sep 27, 2017· Plant availability suffered due to shutdowns and unscheduled maintenance. The dampers would either be locked shut or left open. The burners would end up with either too much air or not enough. Improper combustion led to unburned coal being exhausted into the environment and hot spots damaging boiler tubes.

To increase the co-firing ratio of biomass in existing pulverized coal-fired power plants, biomass should be pulverized to obtain a particle size suitable for combustion. However, evaluation of the particle size distribution of each coal and biomass mixture via traditional fuel analysis is difficult. Because coal does not contain neutral sugars, the particle size distribution of biomass in the
Each plant is fired with sub-bituminous coal from the powder river basin (PRB) (see Table 9.3 for coal properties) and sized to generate 750 MW of net power. The flue gas temperature exiting the air heaters of all four boilers is 121 °C (250 °F) and the boiler efficiency is 87.2% (HHV).
