Abstract
Abstract A hearth apparatus for use in combination with a pyrolysis chamber for waste disposal adapted to support and provide conditions for efficient combustion, pyrolytic decomposition and ensuing removal of the resulting waste residue which comprises at least a pair of oppositely disposed elongated sloping refractory walls which are spaced by and terminate in an elongated openably closed bottom to form a trough-like structure, a plurality of tubes connected to a pressurized air supply passing through the sloping walls providing air sufficient to maintain proper combustion and to fluidize and move pulverulent residue down the sloping walls to a storage area or discharge.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
109 words
A hearth structure in combination with a pyrolytic waste combustion chamber wherein the hearth structure comprises at least a pair of oppositely disposed elongated sloping walls comprising refractory material which are spaced by and terminate in an elongated openably closed bottom to form a resulting trough-shaped assembly, a plurality of tubes connected to a controlled pressurized air supply through said sloping walls at longitudinally and transversely spaced intervals providing air sufficient to maintain proper waste combustion and fluidization of resulting combusted ash residue, and wherein another pair of similarly oppositely disposed elongated sloping walls are provided by at right angles to the original said pair of oppositely disposed walls.
Claim 2
Dependent Claim
109 words
A hearth structure in combination with a pyrolytic waste combustion chamber wherein the hearth structure comprises at least a pair of oppositely disposed elongated sloping walls comprising refractory material which are spaced by and terminate in an elongated openably closed bottom to form a resulting trough-shaped assembly, a plurality of tubes connected to a controlled pressurized air supply through said sloping walls at longitudinally and transversely spaced intervals providing air sufficient to maintain proper waste combustion and fluidization of resulting combusted ash residue, and wherein another pair of similarly oppositely disposed elongated sloping walls are provided by at right angles to the original said pair of oppositely disposed walls.
Claim 3
Dependent Claim
22 words
A hearth structure according to claim 1 wherein all of said oppositely disposed walls terminate in an form an openable bottom hearth.
Claim 4
Dependent Claim
24 words
A hearth structure according to claim 1 wherein said similarly oppositely disposed walls are each inclined at an angle between about 20*0 and 60*.
Claim 5
Dependent Claim
22 words
A hearth structure according to claim 1 wherein all said sloping walls are inclined at an angle between about 20* and 60*.
