Abstract
Abstract An incinerator suitable for the thermal disposal of raw sewage and the like generally comprising a housing having a primary combustion chamber, a secondary combustion chamber and a mixing chamber intercommunicating the primary and secondary combustion chambers, the housing having means for charging waste material into the primary chamber, a burner mounted on the housing, the burner including means for injecting a jet flame through the primary combustion chamber and toward the mixing chamber whereby the flame would ignite the waste material in the primary combustion chamber producing combustion gases, vaporize any liquid constituent of the waste material, produce a draft in the primary combustion chamber causing the flow of the combustion gases and vapor toward and through the mixing chamber, into the secondary combustion chamber, and igniting the combustion gases and vapor for secondary combustion in the secondary combustion chamber, and a flue mounted on the housing for conducting residual combustion gases from the secondary combustion chamber to the ambient atmosphere.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
165 words
An incinerator for the thermal disposal of raw sewage such as human waste and the like comprising a housing having a primary combustion chamber, a secondary combustion chamber and a mixing chamber intercommunicating said primary and secondary combustion chambers, said housing having means for charging waste material into said primary combustion chamber, a burner mounted on said housing, said burner including means for injecting a flame through said primary combustion chamber and toward said mixing chamber whereby said flame functions to ignite said waste material producing combustion gases, vaporize any liquid constituents of said waste material, produce an induced draft in said primary combustion chamber causing the flow of said combustion gases and said vapor toward and through said mixing chamber, into said secondary combustion chamber, and igniting said mixture of said vapopr and combustion gases for secondary combustion in said secondary combustion chamber, and a flue mounted on said housing for conducting residual combustion gases from said secondary combustion chamber to the ambient atmosphere.
Claim 2
Dependent Claim
165 words
An incinerator for the thermal disposal of raw sewage such as human waste and the like comprising a housing having a primary combustion chamber, a secondary combustion chamber and a mixing chamber intercommunicating said primary and secondary combustion chambers, said housing having means for charging waste material into said primary combustion chamber, a burner mounted on said housing, said burner including means for injecting a flame through said primary combustion chamber and toward said mixing chamber whereby said flame functions to ignite said waste material producing combustion gases, vaporize any liquid constituents of said waste material, produce an induced draft in said primary combustion chamber causing the flow of said combustion gases and said vapor toward and through said mixing chamber, into said secondary combustion chamber, and igniting said mixture of said vapopr and combustion gases for secondary combustion in said secondary combustion chamber, and a flue mounted on said housing for conducting residual combustion gases from said secondary combustion chamber to the ambient atmosphere.
Claim 3
Dependent Claim
27 words
An incinerator according to claim 1 wherein said primary combustion chamber includes a trough for receiving liquid constituents of waste material charged into the primary combustion chamber.
Claim 4
Dependent Claim
39 words
An incinerator according to claim 2 wherein said primary combustion chamber includes a hearth on which waste material charged into saiD primary combustion chamber is received and wherein said trough is disposed between said hearth and said mixing chamber.
Claim 5
Dependent Claim
19 words
An incinerator according to claim 3 wherein said hearth includes at least one surface inclined downwardly toward said trough.
Claim 6
Dependent Claim
36 words
An incinerator according to claim 3 wherein said means for charging waste material into said primary combustion chamber consists of an access opening in said housing communicating with said primary combustion chamber, having a closing door.
Claim 7
Dependent Claim
102 words
An incinerator according to claim 1 wherein said primary combustion chamber includes a hearth on which waste material charged into said primary combustion chamber may be deposited, said primary combustion chamber includes a trough disposed between said hearth and said mixing chamber for receiving liquid constituents of waste material charged into the primary combustion chamber and deposited on said hearth, said hearth includes at least one surface inclined downwardly toward said trough, and said means for charging waste material into said primary combustion chamber consists of an access opening in said housing communicating with said primary combustion chamber, having a closing door.
Claim 8
Dependent Claim
14 words
An incinerator according to claim 1 wherein said mixing chamber has a frusto-conical configuration.
Claim 9
Dependent Claim
32 words
An incinerator according to claim 1 wherein said means for injecting a flame includes means for injecting said flame through said primary combustion chamber and at least partially into said mixing chamber.
Claim 10
Dependent Claim
25 words
An incinerator according to claim 1 wherein said means for injecting a flame comprises a nozzle which directs a flame jet toward said mixing chamber.
Claim 11
Dependent Claim
143 words
An incinerator according to claim 1 wherein said flue comprises an exhaust conduit intercommunicating said secondary combustion chamber and the ambient atmosphere, and inner sleeve providing a passageway between said exhaust conduit and said inner sleeve, a lower end of said passageway between said exhaust conduit and said inner sleeve being closed, the upper end of said inner sleeve terminating below the upper end of said exhaust conduit, and an outer sleeve providing a passageway between said exhaust conduit and inner sleeve and said outer sleeve, a lower end of said outer sleeve terminating below the upper end of said inner sleeve, said inner sleeve having a plurality of circumferentially spaced openings through which ambient air may be drawn and induced to flow upwardly between said passageways between said exhaust conduit and said inner sleeve and said exhaust conduit and said outer sleeve.
Claim 12
Dependent Claim
95 words
A incinerator according to claim 1 wherein said flue comprises an exhaust conduit intercommunicating said secondary combustion chamber and the ambient atmosphere, and at least one sleeve providing a passageway between said exhaust conduit and said sleeve, closed at a lower end thereof, and means intercommunicating a lower end of said passageway between said exhaust conduit and said sleeve and an intake of said burner whereby ambient air is induced to flow through said passageway between said exhaust conduit and sleeve, through said intercommunicating means and into said burner intake as preheated primary combustion air.
Claim 13
Dependent Claim
17 words
An incinerator according to claim 1 wherein said exhaust conduit is fabricated of a fire resistant material.
