Calculation of coal handling plant and bunker capacity

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) Coal consumed =3200 X 25 / 4900 = 16.32 MT/hour
