Abstract
Abstract An incinerator of industrial and commercial type comprising a vertical combustion chamber arranged to receive processed waste material of combustible nature, including trash and garbage, and discharge the same upwardly through the bottom of the chamber for initial combustion by a primary burner surrounding the inlet to the chamber, the exhaust for products of combustion being positioned adjacent the top of the chamber and a horizontal separator being positioned in spaced relationship to the inlet to the exhaust means operable to cool the gases of combustion and also deflect solid material back to the combustion zone, and ash discharge means located in the bottom of the combustion chamber for discharge into a quenching pool having conveyor means to remove the quenched ash upwardly for discharge to suitable disposal means.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
217 words
An incinerator for completely burning all ignitable portions of waste material delivered thereto and comprising in combination, a vertical circular combustion chamber, waste inlet means positioned substantially centrally of the bottom thereof and directed vertically upward into said chamber, means to direct a primary combustion air stream under pressure to said waste inlet means and also entrain and propel waste material through said inlet means, a primary burner surrounding said inlet means, means to deliver carbonaceous fuel to said primary burner, exhaust means at the top of said chamber to discharge products of complete combustion, a horizontal heat-resistant separator member spaced below Said exhaust means and substantially coaxial therewith and the periphery thereof being spaced from the inner surface of said chamber to define an annular passage for products of combustion to said exhaust means, said separator being operable to cause solid particles to be deflected to said annular passage and intensify the combustion thereof, means to induce a flame vortex in the combustion chamber to enhance combustion, ash-receiving means paced radially outward from and arranged around said primary burner and comprising a series of funnelshaped openings depending downwardly from the bottom of said chamber, and means adapted to feed waste material to said air stream for delivery thereof to said waste inlet means and said burner.
Claim 2
Dependent Claim
217 words
An incinerator for completely burning all ignitable portions of waste material delivered thereto and comprising in combination, a vertical circular combustion chamber, waste inlet means positioned substantially centrally of the bottom thereof and directed vertically upward into said chamber, means to direct a primary combustion air stream under pressure to said waste inlet means and also entrain and propel waste material through said inlet means, a primary burner surrounding said inlet means, means to deliver carbonaceous fuel to said primary burner, exhaust means at the top of said chamber to discharge products of complete combustion, a horizontal heat-resistant separator member spaced below Said exhaust means and substantially coaxial therewith and the periphery thereof being spaced from the inner surface of said chamber to define an annular passage for products of combustion to said exhaust means, said separator being operable to cause solid particles to be deflected to said annular passage and intensify the combustion thereof, means to induce a flame vortex in the combustion chamber to enhance combustion, ash-receiving means paced radially outward from and arranged around said primary burner and comprising a series of funnelshaped openings depending downwardly from the bottom of said chamber, and means adapted to feed waste material to said air stream for delivery thereof to said waste inlet means and said burner.
Claim 3
Dependent Claim
50 words
The incinerator according to claim 1 further including inlet means intermediately between the top and bottom of said combustion chamber and operable to be connected to a supply of air under pressure to deliver secondary air to said combustion chamber to enhance complete combustion of waste material within said chamber.
Claim 4
Dependent Claim
69 words
The incinerator according to claim 2 in which said inlet for secondary air is disposed tangentially with respect to the walls of said combustion chamber and thereby being operable to produce a swirling movement of combustion gases within the combustion zone of said chamber to render the combustion of waste material efficient by retarding the upward movement thereof and provide a vortex which also effects efficiency in the separator.
Claim 5
Dependent Claim
58 words
The incinerator according to claim 1 further including an additional burner adjacent the upper portion of said combustion zone and operable to effect secondary combustion in the upper portion of said combustion zone when substantially complete combustion of the consumable ingredients of the waste material introduced into such combustion zone has not been effected by said primary burner.
Claim 6
Dependent Claim
44 words
The incinerator according to claim 4 further including a smoke detector adjacent and said exhaust means in the upper portion of said combustion chamber and operable to ignite said secondary burner in response to smoke existing in the upper portion of said combustion zone.
Claim 7
Dependent Claim
57 words
The incinerator according to claim 1 further including a heat exchanger in said exhaust means of said chamber, air supply means connected thereto, and a conduit extending from said heat exchanger and communicating with said waste inlet means and operable to introduce warm air thereto to facilitate the combustion of said waste material by said primary burner.
Claim 8
Dependent Claim
47 words
The incinerator according to claim 1 further including a quenching pool positioned beneath the bottom of said combustion chamber and operable to receive ash material received from said ash-receiving means and operable to quench the same and provide a seal against the escape of products of combustion.
Claim 9
Dependent Claim
30 words
The incinerator according to claim 7 further including conveyor means operable to receive quenched ash material and move the same upwardly from said quenching pool for discharge to disposal means.
Claim 10
Dependent Claim
37 words
The incinerator according to claim 8 further including control means operable to regulate the water level in said pool, said control means being adjacent the discharge end of said conveyor means for ready access to regulation thereof.
Claim 11
Dependent Claim
54 words
The incinerator according to claim 7 in which said ash-receiving means comprises a plurality of discharge ports arranged in circular pattern around the bottom of said combustion hopper and further including a central hopper device operable commonly to receive discharge from all of said discharge ports, said hopper being positioned within said quenching pool.
Claim 12
Dependent Claim
20 words
The incinerator according to claim 10 in which said hopper communicates with the lower end of said ash conveyor means.
