Method of incinerating refuse

Abstract

Abstract A METHOD AND APPARATUS FOR INCINERATING SOLID REFUSE IN WHICH LAREGE AMOUNTS OF USEFUL BY-PRODUCTS ARE RECOVERED AND WHICH IS SUBSTANTIALLY AIR POLLUTION FREE. THE INCINERATOR INCLUDES A FEED-SHAFT, A COMBUSTION CHAMBER INCLUDING A LOW TEMPERATURE, MEDIUM TEMPERATURE AND HIGH TEMPERATURE ZONE HAVING A REDUCING ATMOSPHERE, AND A CHEMICAL REACTION ZONE HAVING AN OXIDIZING ATMOSPHERE. UNSORTED REFUSE ALONG WITH SELECTED ADDITIVES ARE PLACED INTO THE INCINERATOR ON TOP OF A COKE-BED IN THE HIGH TEMPERATURE ZONE. DURING INCINERATION, DISTILLATES FROM LOW TEMPERATURE PYROLYSIS IN THE LOW TEMPERATURE ZONE, AND HIGH TEMPERATURE PYROLYSIS IN THE MEDIUM TEMPERATURE ZONE, ARE WITHDRAWN THROUGH CONDENSERS. A VARI ABLE SPEED FAN OPERABLY EXHAUSTING THE CHEMICAL REACTION ZONE IS OPERATED TO CREATE A NEUTRAL PRESSURE POINT BETWEEN THE MEDIUM TEMPERATURE AND THE HIGH TEMPERATURE ZONE WHEREBY THE PYROLYSIS DISTILLATES MAY BE EASILY SEPARATED FROM A STREAM OF HIGH TEMPERATURE VOLATILES AND CO PRODUCED IN THE HIGH TEMPERATURE ZONE. THE STREAM OF AIR BLOWING ACROSS THE REFUSE CARRIERS THE HIGH TEMPERATURE VOLATILES INTO THE CHEMICAL REACTION ZONE. THE CHEMICAL REACTION ZONE HAS A CHECKER-WALL CONSTRUCTED OF VARIOUS BRICKS SO THAT THE VOLATILES REACT WITH THE BRICKS TO FORM BASIC AND ACIDIC SLAG OXIDES. THE SLAG OXIDES CONDENSE AND FLOW INTO THE HEARTH OF THE HIGH TEMPERATURE ZONE. MOLTEN IRON COLLECTS IN THE INTERSTICES OF THE COKE-BED AND IS REMOVED BY CASTING.
