Read MoreTypical power plant flue gas volumes range from 3000 to 4000 acfm/MW depending on coal composition, boiler heat rate, gas temperature, and amount of excess air. Because of economies of scale, the utility industry has tended toward larger and larger power stations implying that scrubber systems must be capable of handling volumes of gas as large
