Apparatus for making carbon black

Claim 1

AN APPARATUS FOR PRODUCING CARBON BLACK WHICH COMPRISES: (A) AN ELONGATE TUBULAR METALLIC HOUSING HAVING A DOWNSTREAM END AND AN UPSTREAM END, THE LATTER BEING PROVIDED WITH A CLOSURE MEMBER; (B) AN OPEN ELONGATE TUBULAR METALLIC REACTOR OF LESSER DIAMETER AND LENGTH THAN SAID HOUSING SUPPORTED SUBSTANTIALLY CONCENTRICALLY THEREIN WITH THE CORRESPONDING DOWNSTREAM ENDS OF THE REACTOR AND HOUSING ARRANGED IN SUBSTANTIAL FLUSH ALIGNMENT THEREBY PROVIDING AN ANNULAR SPACING ABOUT THE REACTOR TUBE FOR THE LENGTH THEREOF AND A GENERALLY CYLINDRICAL CHAMBER HAVING A LENGTH SUBSTANTIALLY LESS THAN THAT OF THE REACTOR BETWEEN THE CORRESPONDING UPSTREAM ENDS OF THE REACTOR AND HOUSING; (C) A HEAT-CONDUCING REFRACTORY MEANS LINING THE REACTOR, SAID MEANS SHAPED TO PROVIDE A VENTURI CONFIGURATION WHOSE THROAT SECTION IS DISPOSED TOWARD THE UPSTREAM END OF THE REACTOR AND WHOSE OVERALL LENGTH OF CONVERGENT, THROAT AND DIVERGENT SECTIONS IS SUBSTANTIALLY LESS THAN THAT OF THE REACTOR; (D) AIR INPUT MEANS DISPOSED TOWARD THE DOWNSTREAM END OF SAID HOUSINGD AND ADAPTED TO FORCE AIR THROUGH SAID ANNULAR SPACING INTO SAID CHAMBER; (E) A FUEL BURNER SUBSTANTIALLY CONCENTRICALLY DISPOSED WITHIN SAID CHAMBER; AND (F) A CONCENTRICALLY DISPOSED CARBON BLACK PRODUCING FEEDSTOCK INJECTION MEANS POSITIONED WITHIN SAID REACTOR UPSTREAM WITH RESPECT TO THE THROAT OF SAID VENTURI CONFIGURATION.

Claim 2

AN APPARATUS FOR PRODUCING CARBON BLACK WHICH COMPRISES: (A) AN ELONGATE TUBULAR METALLIC HOUSING HAVING A DOWNSTREAM END AND AN UPSTREAM END, THE LATTER BEING PROVIDED WITH A CLOSURE MEMBER; (B) AN OPEN ELONGATE TUBULAR METALLIC REACTOR OF LESSER DIAMETER AND LENGTH THAN SAID HOUSING SUPPORTED SUBSTANTIALLY CONCENTRICALLY THEREIN WITH THE CORRESPONDING DOWNSTREAM ENDS OF THE REACTOR AND HOUSING ARRANGED IN SUBSTANTIAL FLUSH ALIGNMENT THEREBY PROVIDING AN ANNULAR SPACING ABOUT THE REACTOR TUBE FOR THE LENGTH THEREOF AND A GENERALLY CYLINDRICAL CHAMBER HAVING A LENGTH SUBSTANTIALLY LESS THAN THAT OF THE REACTOR BETWEEN THE CORRESPONDING UPSTREAM ENDS OF THE REACTOR AND HOUSING; (C) A HEAT-CONDUCING REFRACTORY MEANS LINING THE REACTOR, SAID MEANS SHAPED TO PROVIDE A VENTURI CONFIGURATION WHOSE THROAT SECTION IS DISPOSED TOWARD THE UPSTREAM END OF THE REACTOR AND WHOSE OVERALL LENGTH OF CONVERGENT, THROAT AND DIVERGENT SECTIONS IS SUBSTANTIALLY LESS THAN THAT OF THE REACTOR; (D) AIR INPUT MEANS DISPOSED TOWARD THE DOWNSTREAM END OF SAID HOUSINGD AND ADAPTED TO FORCE AIR THROUGH SAID ANNULAR SPACING INTO SAID CHAMBER; (E) A FUEL BURNER SUBSTANTIALLY CONCENTRICALLY DISPOSED WITHIN SAID CHAMBER; AND (F) A CONCENTRICALLY DISPOSED CARBON BLACK PRODUCING FEEDSTOCK INJECTION MEANS POSITIONED WITHIN SAID REACTOR UPSTREAM WITH RESPECT TO THE THROAT OF SAID VENTURI CONFIGURATION.
