In stacking process crushed coal are stored in a yard. This process is generally used when boiler bunker level is full. In reclaiming process the stored coal are reclaimed for sending to boiler bunkers. This process is used when boiler bunker level is low. Both the process ( stacking reclaiming) is achieved by stacker cum reclaimer.

Another advantage is that cofiring diversifies the coal plant's fuel portfolio and it can help to dispose of a solid waste. More than 150 power plants worldwide have experience of cofiring biomass or waste fuels, at least on a trial basis. There are approximately 40 pulverised coal combustion (PCC) plants that cofire biomass

Closed coal bunkers emerged as a novel form of coal storage for coalfired power stations. Nevertheless, heat builds continually in the storage process because of the constant oxidation of coal and combined with the impact of a confined coal bunker environment, it is difficult for heat to dissipate, resulting in frequent coal bunker fires. Consequently, research on coal pile combustion ...
