We shall calculate the coal handling & bunker capacity by taking an example of 25 MW thermal power plant consuming coal of GCV 4900 kcal/kg & having heat rate 3200 kcal/kwh running at 100% PLF. Plant running load = 50 MW X 100/100 = 25 MW. We know that coal consumed = Heat rate X Power generation / (Coal GCV)
