Carbon black apparatus

Claim 1

A REACTOR FOR PPRODUCTING CARBON BLACK BY THERMAL DECOMPOSITING OF A HYDROCARBON FEEDSTOCK WHICH COMPRISES: A TUBULAR COMBUSTION CHAMBER HAVING A DIMETER GREATER THAN ITS LENGTH COMMUNICATING AXIALLY THROUGH ONE OF ITS ENDS WITH A TUBULAR REACTION CHAMBER OF SMALLER DIAMETER AND GREATER LENGTH THAN SAID SOMBUSTION CHAMBER; A HYDROCARBON FEEDSTOCK CONDDUIT EXTENDING THROUGH THE OTHER END OF SAID COMBUSTION CHAMBER AND COMPLETELY ACROSS THE WIDTH THEREOF FOR INTRODUCTING HYDROCACBON FEEDSTOCK AXIALLY INTO SAID REACTION CHAMBER, SAID CONDUIT FORMING AN ANNULUS WITH THE CIRCUMFERENTIAL WALL OF SAID COMBUSTION CHAMBER; AT LEAST ONE INJECTION MEANS TANGENTIALLY DISPOSED WITH RESPPECT TO THE CIRCUMFERNTIAL WALL OF THE SAID COMBUSTION CHAMBER AND COMMUNICATING THEREWITH FOR TANGENTIALLY INJECTION A STREAM OF A COMBUSTIBLE MIXTURE INCLUDING BY GIVING SAID STREAM OF COMBUSTIBLE MIXTURE INCLUDING THE COMBUSTION MASS RESULTING FROM THE COMBUSTION THEREOF A ROTATIONAL FLOW; SAID COMBUSTION CHAMBER AND CONDUIT PROVIDING SAID ANNULUS WITH A PROGRESSIVELY DECREASING CROSS-SECTIONAL AREA FROM THE POINT AT WHICH SAID INJECTION MEANS A TANGENTIALLY DISPOSED WITH RESPECT TO SAID CIRCUMFERCENTIAL WALL IN THE DIRECTION OF FLOW OF SAID TANGENTIALLY INJECTED STREAM WHEREBY THE ROTATIONAL VELOCITY OF SAID STREAM IS ACCELERTED; AND MEANS FOR DIRECTING SAID ROTATIONALLY FLOWING STREAM INTO SAID REACTIOM CHAMBER.
