For renewable electricity production, biomass can fully displace coal in an existing power plant with some equipment modifications. Recently, a 125 MWe power plant burning mainly anthracite in Korea was retrofitted for dedicated wood pellet combustion with a change of boiler configuration from arch firing to wall firing. However, this boiler suffers from operational problems caused by

The reason why Pulverized Coal is the preferred form of coal to use is that it flows like natural gas, provides flexible control and combustion is cleaner and more complete. To be considered as Pulverized Coal, coal is finely ground so that approximately 75% of the Pulverized Coal ( by weight) passes through a 200-mesh screen.
