Abstract
An emission control fluidized bed reactor is disclosed. The reactor includes a central chamber with a fluidized bed at the base of the central chamber and circulating particulate matter above the fluidized bed forming a freeboard. The fluidized bed is maintained at a temperature range between 1500.degree. F. and 1600.degree. F. The freeboard is operated in a predetermined environment between 1600.degree. F. and 1700.degree. F. and with a velocity between 4 to 12 feet per second. An externally fed gas from a discrete industrial process such as an external combustion system or a plant process is conveyed into the freeboard. The externally fed gas includes pollutants which are suppressed as a result of the predetermined environment in the freeboard.
