Process and apparatus for manufacture of carbon black

Claim 2

IN THE PROCESS FOR PRODUCING CARBON BLACK BY DECOMPOSING HYDROCARBONS WHEREBY THE HYDROCARBON TO BE DECOMPOSED IS SEPARATELY INJECTED AS A LIQUID SPRAY DIRECTLY INTO A STREAM OF HOT BLAST FLAME GASES PASSING AT HIGH VELOCITY IN A HELICAL PATH THROUGH AN ELONGATED HEAT-INSULATED REATION CHAMBER AND IS RAPIDLY MIXED THEREWITH AND IS DECOMPOSED BY HEAT ABSORBED FROM THE HOT GASES TO FORM CARBON BLACK IN SUSPENSION, THE SUSPENSION BEING WITHDRAWN FROM THE DOWNSTREAM END OF SAID CHAMBER AND THE CARBON BLACK SEPARATED AND COLLECTED, THE STEPS OF SEPARATELY BURNING A FLUID FUEL AND AN OXYGEN-CONTAINING GAS BY INJECTING THE FUEL SUNSTANTIALLY AXIALLY INTO ONE END OF A CYLINDRICAL COMBUSTION CHAMBER OF GREATER LENGTH THAN DIAMETER, WHILE DIRECTING AIR SUBSTANTIALLY TANGENTIALLY INTO SAID EN OF THE COMBUSTION CHAMBER, AND THEREBY MIXING THE FUEL AND AIR AND BURNING THE FUEL TO AT LEAST 90% COMPLETE COMBUSTION AS IT PASSES THROUGH THE COMBUSTION CHAMBER TO PRODUCE A HOT, HIGH-VELOCITY GAS STREAM SUBSTANTIALLY FREE FROM UNCONSUMED FUEL AND DELIVERING SAID STREAM OF HOT GASES TANGENTIALLY INTO THE UPSTREAM END OF THE REACTION CHAMBER.

Claim 3

APPARATUS FOR PRODUCING CARBON BLACK COMPRISING AN ELONGATED, HEAT-INSULATED REACTION CHAMBER OF CYLINDRICAL CROSS-SECTION ADAPTED TO BE CONNECTED AT ITS DOWNSTREAM END TO A COOLING AND COLLECTING SYSTEM, AT LEAST ONE ELONGATED SUBSTANTIALLY CYLINDRICAL COMBUSTION CHAMBE OPENING AT ONE END TANGENTIALLY INTO THE UPSTREAM END OF SAID REACTION CHAMBER, AND COMPRISING AN OUTER PORTION OF A LENGTH LESS THAN ITS DIAMETER, CLOSED AT ITS UPSTREAM END AND IN OPEN COMMUNICATION AT ITS DOWNSTREAM END WITH A COAXIALLY POSITIONED, UNRESTRICTED PORTION OF SUNSTANTIALLY UNIFORM CROSS-SECTIONAL AREA HAVING A DIAMETER LESS THAN THE DIAMETER OF THE SAID OUTER PORTION AND OF A LENGTH GREATER THAN ITS DIAMETER, MEANS FOR INJECTING AT LEAST ONE STREAM OF AIR TANGENTIALLY INTO SAID ENLARGED OUTER PORTION OF THE COMBUSTION CHAMBER, A FUEL INJECTOR EXTENDING SUBSTANTIALLY COAXIALLY CHAMBER, A FUEL END OF THE COMBUSTION CHAMBER AND DISCHARGING INTO THE SAID OUTER PORTION OF THE COMBUSTION CHAMBER INTERMEDIATE THE LENGTH THEREOF, MEANS FOR INJECTING HYDROCARBON MAKE SUBSTANTIALLY RADIALLY INTO THE REACTION CHAMBER NEAR THE UPSTREAM END THEREOF BUT DOWNSTREAM FROM THE ENTRANCE OF THE COMBUSTION CHAMBER THERETO.

Claim 4

APPARATUS FOR PRODUCING CARBON BLACK COMPRISING AN ELONGATED, HEAT-INSULATED REACTION CHAMBER OF CYLINDRICAL CROSS-SECTION ADAPTED TO BE CONNECTED AT ITS DOWNSTREAM END TO A COOLING AND COLLECTING SYSTEM, AT LEAST ONE ELONGATED SUBSTANTIALLY CYLINDRICAL COMBUSTION CHAMBE OPENING AT ONE END TANGENTIALLY INTO THE UPSTREAM END OF SAID REACTION CHAMBER, AND COMPRISING AN OUTER PORTION OF A LENGTH LESS THAN ITS DIAMETER, CLOSED AT ITS UPSTREAM END AND IN OPEN COMMUNICATION AT ITS DOWNSTREAM END WITH A COAXIALLY POSITIONED, UNRESTRICTED PORTION OF SUNSTANTIALLY UNIFORM CROSS-SECTIONAL AREA HAVING A DIAMETER LESS THAN THE DIAMETER OF THE SAID OUTER PORTION AND OF A LENGTH GREATER THAN ITS DIAMETER, MEANS FOR INJECTING AT LEAST ONE STREAM OF AIR TANGENTIALLY INTO SAID ENLARGED OUTER PORTION OF THE COMBUSTION CHAMBER, A FUEL INJECTOR EXTENDING SUBSTANTIALLY COAXIALLY CHAMBER, A FUEL END OF THE COMBUSTION CHAMBER AND DISCHARGING INTO THE SAID OUTER PORTION OF THE COMBUSTION CHAMBER INTERMEDIATE THE LENGTH THEREOF, MEANS FOR INJECTING HYDROCARBON MAKE SUBSTANTIALLY RADIALLY INTO THE REACTION CHAMBER NEAR THE UPSTREAM END THEREOF BUT DOWNSTREAM FROM THE ENTRANCE OF THE COMBUSTION CHAMBER THERETO.
