Abstract
815,725. Combustion apparatus ; recirculating combustion gases. COMBUSTION ENGINEERING Inc. April 30, 1956 [June 21, 1955], No. 13160/56. Class 51 (1). [Also in Group XIII] Fuel is burnt in a boiler furnace in the presence of oxygen and recirculated combustion gases. As shown, pulverized coal is blown into a combustion chamber 4A, Fig. 1, through nozzles 42, Fig. 2, in a recirculated gas stream taken from the boiler gas-flow path by a fan 52 and blown through pipes 60, 56, entraining the coal in the latter pipe as it drops from a hopper 54. Oxygen from a vessel 66 is mixed with the coal and gas before its discharge through the nozzles 42 in such proportions that incomplete combustion ensures and the products, passing through a throat 46 into a combustion chamber 4B, contain a large amount of combustibles. Before its passage through the throat 46 additional gas-borne pulverised coal is added to the combustible mixture through tangentiallydirected nozzles 44. Preferably the nozzle sets 42, 44 are disposed to fire in opposite directions. The gases passing through the chamber 4B are cooled by a high-temperature reheater 30 before admixture with tangentially introduced streams of mixed recirculated gas and oxygen issuing through nozzles 45. The resulting products of complete combustion then pass to a chimney via a high-temperature superheater 20, a low-temperature superheater 16, a low-temperature reheater 26 and an economizer 48. Individual control of superheat and reheat steam temperatures may be effected by controlling the proportions of recirculated gas and oxygen passed into the chambers 4A, 4B. Reheat and superheat temperature variations are recorded by respective devices 80, 84, the temperature impulses received by them being translated into mechanical motion operative in oxygen adjusting valves 82, 78, and recirculated gas dampers 74, 72, by known electric, pneumatic or hydraulic devices 92, 90, 86, 88. Specification 815,724 is referred to.
