Transfer line burner system

Claim 1

IN A PROCESS WHEREIN A SOLIDS STREAM CONSISTING ESSENTIALLY OF CARBONACEOUS PARTICLES WITHDRW FROM A FLUIDIZED BED REACTORS IS CONTACTED WITH AN OXYGEN-CONTAINING GAS IN A TRANSFER LINE BURNER TO BURN CARBON PRESENT IN SAID PARTICLES AND RAISE THE TEMPERATURE OF SAID STREAM, WHEREIN HEATED PARTICLES AND COMBUSTION GASES CONTAINING CARBON MONOXIDE ARE WITHDRAW OVERHEAD FROM SAID TRANSFER LINE BURNER, AND WHEREIN SAID HEATED PARICLES ARE SEPARATED FROM SAID COMBUSTION GASES AND RETURNED TO SAID FLUIDIZED BED REACTOR; THE IMPROVEMENT WHICH COMPRISES INTRODUCING A FIRST STREAM OF OXYGEN-CONTAINING GAS INTO SAID TRANSFER LINE BURNER AT A POINT NEAR THE LOWER END THEREOF IN A QUANTITY SUFFICIENT TO INITATE THE COMBUSTION OF CARBON IN SAID PARTICLES INTRODUCING ADDITIONAL OXYGEN-CONTAINING GAS INTO SAID BURNER AT A SECOND POINT NEAR THE LOWER END OF SAID BURNER IN A QUANTITY SUFFICIENT TO BURN CARBON MONOXIDE PRESENT IN THE COMBUSTION GASES REACHING SAID SECOND POINT AND GENERATE ADDITIONAL HEAT, MONITORING THE CARBON MONOXIDE CONTENT OF THE COMBUSTION GASES WITHDRAWN FROM SAID BURNER, REGULATING THE RELATIVE QUANTITIES OF OXYGEN-CONTAINING GAS INTRODUCED INTO SAID BURNER AT SAID FIRST POINT AND SAID SECOND POINT IN RESPONSE TO CHANGES IN THE CARBON MONOXIDE CONTENT OF SAID COMBUSTION GASES WITHDRAWN FROM SAID BURNER, AND CONTROLLING THE TOTAL AMOUNT OF OXYGEN-CONTAINING GAS INTRODUCED INTO SAID BURNER IN RESPONSE TO CHANGES IN THE TEMPERATURE IN SAID FLUIDIZED BED REACTOR.
