Increasing efficiency of pulverised coal-fired power ...
2021-4-26 Many factors impact unit efficiency, including design and operating parameters and coal quality. The current global average is 37.5 % (LHV, net), whereas state-of-the-art plants achieve efficiencies of over 47%. This means that around 2 GtCO2/y emissions could be saved if the gap between the average and the state-of-the-art power plant was closed.

Pulverizer Capacity is not simply “tons throughput per
2016-5-3 pulverizer capacity. Capacity of a pulverizer is a minimum of five factors and these five factors are: tons throughput at a given fineness, at a given Hardgrove grindability index (HGI), at a given raw coal sizing entering the mill and at a given coal moisture content. Throughput alone is NOT a definition of pulverizer capacity! Please read on
