A new type of industrial air heating system developed by FluiDyne Engineering Corporation utilizing a fluidized bed combustor is described. In the combustor, coal is burned in a fluidized bed of crushed limestone or dolomite sorbent. The sorbent absorbs the sulfur dioxide (SO/sub 2/) and yields a dry calcium sulfate by-product. The same unit is adaptable to burning inexpensive fuels such as waste wood and paper or petroleum coke. An FBC air heater provides a clean, uncontaminated source of high-temperature air or gases for use in industrial processing. Heated air (up to 1000/sup 0/F) is supplied by two heat exchangers, one in the fluidized bed combustor and another in the flue gas. Capacities up to 13 million Btu/h are possible with this system. The flue-gas heat exchanger can also be designed for heating water or other liquids rather than air. The main advantages of FBC heating systems are flexibility in using alternate fuels, pollution control, and alternative uses for the combustion by-products. A unit can burn all types of coal regardless of sulfur content, plant wood, and paper wastes.
