Abstract

1415594 Oxygen-enriched hot blast BLACK SIVALLS & BRYSON Inc 30 Jan 1973 [19 Oct 1972] 4521/73 Heading C7D A stream of fuel gas is combusted with air to provide a stream of exhaust gas at super-atmospheric pressure while oxygen-containing gas is added either to the mixture prior to combustion or to the exhaust stream, the oxygen input rate being controlled as a function of the oxygenenriched output rate, the fuel input rate being controlled as a function of output flow-rate, and the air input rate being controlled as a function of fuel input rate to produce a stoichiometric mixture. As particularly described fuel gas from line 24, and air from blower 28 are combusted in high intensity burner 20 while oxygen from line 38 is introduced tangentially into mixing chamber 30. Flow sensor 44 in the output conduit controls fuel and oxygen inlet valves 40 and 52, while flow sensor 46 controls air inlet valve 50. Suitable fuels are natural gas or coke oven gas.
