A typical coalfired power plant with an electrical output of 500 MW requires about 50 kg s–1 of coal and about 550 kg s–1 of air to produce about 600 kg s–1 of exhaust gas. This, translated into volumetric air and gas volume flow rates at the inlet and outlet, gives about 500 m3 s–1 and 675 m3 s–1 respectively.
