Incineration of industrial waste, and apparatus

Claim 1

THE PROCESS OF PYRO-DECOMPOSING A FLUID WASTE MATERIAL TO CONVERT THE SAME INTO A GASEOUS FULLY DECOMPOSED REACTION PRODUCT, WHICH COMPRISES COMPLETELY DISPERSING WITH PRIMARY AIR, INTO THE BASE OF A VERTICAL CYLINDRICAL ELONGATED SPACE DEFINED IN PART BY REFRACTORY WALLS, THE AXIAL LENGTH OF WHICH SPACE HAS A 5-TO-1 RATIO TO ITS DIAMETER, A FLUID WASTE MATERIAL INCLUDING A COMBUSTIBLE COMPONENT; INITIATING THE COMBUSTION OF THE COMBUSTIBLES OF THE AIR-BORNE DISPERSED FLUID WASTE MATERIAL UPON ITS ENTRY INTO SAID SPACE, THEREBY FORMING A BURNING AEROFORM STREAM; CONTROLLING THE COMBUSTION TO MAINTAIN A MAXIMUM TEMPERATURE WITHIN THE RANGE 2800-3000*F.; MAINTAINING THE AEROFORM CONTENTS OF THE ELONGATED SPACE AT A SUPERATMOSPHERIC PRESSURE CONSISTENT WITH A DESIRED RETENTION TIME FOR THE BURNING STREAM; SURROUNDING THE BURNING STREAM WITH A MANTLE OF SECONDARY AIR MOVING IN AN AXIAL DIRECTION ONLY AND IN THE SAME DIRECTION AS THAT OF AND COEXTENSIVELY WITH SAID STREAM THEREBY PROTECTING SAID REFRACTORY WALLS FROM WASTE MATERIAL IMPINGEMENT; AND COMPLETING THE PYRODECOMPOSITION BY MIXING THE SECONDARY AIR OF SAID MANTLE, IN THE UPPERMOST ZONE OF SAID SPACE, WITH SAID BRUNING STREAM WHEREBY TO DECOMPOSE SAID WASTE MATERIAL AND TO CONVERT THE SAME INTO A GASEOUS REACTION PRODUCT FREE FROM SMOKE, ODOR AND VISIBLE ASH.
