Carbon black furnace dual fluid injector

Claim 2

A DUAL FLUID INJECTOR FOR A CARBON BLACK FURNACE COMPRISING IN COMBINATION A FIRST CERAMIC TUBE CONSTRUCTED AND DISPOSED TO FIT IN A LIQUID INLET OF SAID FURNACE, SAID FIRST TUBE HAVING A VENTURI SHAPED BORE, A SECOND CERAMIC TUBE OF LESSER LENGTH THAN THE CONVERGING PORTION OF SAID VENTURI HAVING A TAPERED EXTERNAL SURFACE ADAPTED AND DISPOSED TO FIT INTO SAID CONVERGING PORTION ADJACENT THE THROAT OF SAID VENTURI, SAID SECOND TUBE HAVING A CYLINDRICAL BORE THE ENDS OF WHICH ARE FLARED OUTWARDLY TO MERGE WITH THE CONVERGING AND DIVERGING SURFACES OF SAID VENTURI TO AID STREAMLINE FLOW OF A FIRST FLUID THERETHROUGH, AND A THIRD TUBE FOR THE INJECTION OF A SECOND FLUID INTO SAID FURNACE EXTENDING FROM THE EXTERIOR OF SAID FURNACE AXIALLY INTO AND SPACED FROM THE INNER CYLINDRICAL WALL OF SAID SECOND TUBE BY RADIAL LUGS SECURED TO SAID THIRD TUBE TO AID THE FLOW OF SAID FIRST FLUID INTO SAID FURNACE THROUGH THE ANNULUS BETWEEN SAID SECOND AND THIRD TUBES.

Claim 3

A CARBON BLACK FURNACE COMPRISING IN COMBINATION A HEAT INSULATING BODY HAVING A REACTION CHAMBER THEREIN, AN INLET AND AN OUTLET PASSAGE COMMUNICATING BETWEEN THE INTERIOR OF SAID CHAMBER AND THE EXTERIOR OF SAID FURNACE, A METALLIC HOUSING AROUND SAID FURNACE, A DUAL FLUID INJECTOR COMPRISING A FIRST CERAMIC TUBE FITTED IN SAID INLET PASSAGE, SAID FIRST TUBE HAVING A VENTURI SHAPED BORE, A SECOND CERAMIC TUBE OF LESSER LENGTH THAN THE CONVERGING PORTION OF SAID VENTURI HAVING A TAPERED EXTERNAL SURFACE ADPATED AND DISPOSED TO FIT INTO SAID CONVERGING PORTION ADJACENT THE THROAT OF SAID VENTURI, SAID SECOND TUBE HAVING A CYLINDRICAL BORE THE ENDS OF WHICH ARE FLARED OUTWARDLY TO MERGE WITH THE CONVERGING AND DIVERGING SURFACES OF SAID VENTURI TO AID STREAMLINE FLOW OF A FIRST FLUID THERETHROUGH, AND A THIRD TUBE FOR THE INJECTION OF A SECOND FLUID INTO SAID FURANCE EXTENDING FROM THE EXTERIOR OF SAID FURNACE AXIALLY INTO AND SPACED FROM THE INNER CYLINDRICAL WALL OF SAID SECOND TUBE BY RADIAL LUGS SECURED TO SAID THIRD TUBE TO AID THE FLOW OF SAID FLUID INTO SAID FURNACE THROUGH THE ANNULUS BETWEEN SAID SECOND AND THIRD TUBES, A FIRST METAL SUPPLY PIPE FOR SAID FIRST FLUID SECURED TO SAID METALLIC HOUSING AROUND AND IN COMMUNICATION WITH THE BORE OF SAID FIRST TUBE, SAID THIRD TUBE PASSING THROUGH THE WALL OF SAID FIRST PIPE AND BEING SUPPORTED THEREBY IN ITS SAID POSITION, AND A SUPPLY PIPE FOR SAID SECOND FLUID SECURED IN COMMUNICATION WITH SAID END OF SAID THIRD TUBE SUPPORTED BY SAID FIRST PIPE.

Claim 4

A CARBON BLACK FURNACE COMPRISING IN COMBINATION A HEAT INSULATING BODY HAVING A REACTION CHAMBER THEREIN, AN INLET AND AN OUTLET PASSAGE COMMUNICATING BETWEEN THE INTERIOR OF SAID CHAMBER AND THE EXTERIOR OF SAID FURNACE, A METALLIC HOUSING AROUND SAID FURNACE, A DUAL FLUID INJECTOR COMPRISING A FIRST CERAMIC TUBE FITTED IN SAID INLET PASSAGE, SAID FIRST TUBE HAVING A VENTURI SHAPED BORE, A SECOND CERAMIC TUBE OF LESSER LENGTH THAN THE CONVERGING PORTION OF SAID VENTURI HAVING A TAPERED EXTERNAL SURFACE ADPATED AND DISPOSED TO FIT INTO SAID CONVERGING PORTION ADJACENT THE THROAT OF SAID VENTURI, SAID SECOND TUBE HAVING A CYLINDRICAL BORE THE ENDS OF WHICH ARE FLARED OUTWARDLY TO MERGE WITH THE CONVERGING AND DIVERGING SURFACES OF SAID VENTURI TO AID STREAMLINE FLOW OF A FIRST FLUID THERETHROUGH, AND A THIRD TUBE FOR THE INJECTION OF A SECOND FLUID INTO SAID FURANCE EXTENDING FROM THE EXTERIOR OF SAID FURNACE AXIALLY INTO AND SPACED FROM THE INNER CYLINDRICAL WALL OF SAID SECOND TUBE BY RADIAL LUGS SECURED TO SAID THIRD TUBE TO AID THE FLOW OF SAID FLUID INTO SAID FURNACE THROUGH THE ANNULUS BETWEEN SAID SECOND AND THIRD TUBES, A FIRST METAL SUPPLY PIPE FOR SAID FIRST FLUID SECURED TO SAID METALLIC HOUSING AROUND AND IN COMMUNICATION WITH THE BORE OF SAID FIRST TUBE, SAID THIRD TUBE PASSING THROUGH THE WALL OF SAID FIRST PIPE AND BEING SUPPORTED THEREBY IN ITS SAID POSITION, AND A SUPPLY PIPE FOR SAID SECOND FLUID SECURED IN COMMUNICATION WITH SAID END OF SAID THIRD TUBE SUPPORTED BY SAID FIRST PIPE.
