Abstract
Abstract The apparatus comprises an integration of structural elements to provide adjacent first and second zones for the destruction of refuse. The first zone is a heat generating zone in which fuel burning heating means are employed to heat a mass of material disposed therein thereby providing a high temperature environment for a second zone communicating therewith. The second zone is an incineration zone for soft refuse such as paper. Materials which do not readily combust fall to the heated mass of material and melt or are otherwise consumed and absorbed. The residue discharges from the incinerator intermittently either as a gas or in molten form by way of removal spouts located in the vicinity of the first zone.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
135 words
An incinerator for destroying refuse and comprising: a first zone defining a heat generating zone and comprising a stationary periphery wall of refractory material for retaining a mass of material in said zone whereupon the upper level of said mass approximately defines the upper boundary of said first zone, and combustion heating means arranged to apply heat exteriorly of said wall for heating said mass; and, a second zone adjacent said first zone, said boundary approximately defining the lower boundary of said second zone, said zone defining primarily an incineration zone and comprising a periphery wall of refractory material, means to introduce refuse material to said zone, and means to introduce a fluid to said zone which in combination with heat from said first zone can cause incineration of material delivered to said second zone.
Claim 2
Dependent Claim
135 words
An incinerator for destroying refuse and comprising: a first zone defining a heat generating zone and comprising a stationary periphery wall of refractory material for retaining a mass of material in said zone whereupon the upper level of said mass approximately defines the upper boundary of said first zone, and combustion heating means arranged to apply heat exteriorly of said wall for heating said mass; and, a second zone adjacent said first zone, said boundary approximately defining the lower boundary of said second zone, said zone defining primarily an incineration zone and comprising a periphery wall of refractory material, means to introduce refuse material to said zone, and means to introduce a fluid to said zone which in combination with heat from said first zone can cause incineration of material delivered to said second zone.
Claim 3
Dependent Claim
15 words
The apparatus of claim 1 wherein said combustion heating means comprises gas flame heating means.
Claim 4
Dependent Claim
20 words
The apparatus of claim 1 wherein said gas flame heating means comprises a plurality of jets surrounding said first zone.
Claim 5
Dependent Claim
29 words
The apparatus of claim 1 including an overflow spout located at a selected boundary between said first and second zones for removing from said incinerator molten products produced therein.
Claim 6
Dependent Claim
19 words
The apparatus of claim 3 wherein the combustion products of said heating means are channeled to said second zone.
Claim 7
Dependent Claim
15 words
The apparatus of claim 4 wherein said overflow spout is heated by said combustion products.
