Abstract
Abstract The method of burning glutinous waste mass in an incinerator wherein the glutinous mass is maintained out of contact with a preheated combustion chamber wall to raise the temperature of the mass and cause partial incineration of the mass and thereby prevent the creation of thermal gradients in the combustion chamber wall. The partially incinerated mass deposited on the wall is then burned to convert the waste to ash. The glutinous waste mass is fed into the furnace at a rate commensurate with the burning rate.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
102 words
The method of incinerating glutinous waste mass in a combustion chamber defined by a wall having an opening through which said glutinous waste mass is deposited into said chamber, said method comprising preheating said combustion chamber to provide heat energy for rapidly raising the temperature of said glutinous waste mass, depositing said glutinous waste mass through the combustion chamber opening, maintaining said waste mass out of contact with the wall of said combustion chamber to partially incinerate said mass for subsequent deposition of partially incinerated mass on said combustion chamber wall and continuing said incineration until said waste is converted to ash.
Claim 2
Independent Claim
102 words
The method of incinerating glutinous waste mass in a combustion chamber defined by a wall having an opening through which said glutinous waste mass is deposited into said chamber, said method comprising preheating said combustion chamber to provide heat energy for rapidly raising the temperature of said glutinous waste mass, depositing said glutinous waste mass through the combustion chamber opening, maintaining said waste mass out of contact with the wall of said combustion chamber to partially incinerate said mass for subsequent deposition of partially incinerated mass on said combustion chamber wall and continuing said incineration until said waste is converted to ash.
Claim 3
Dependent Claim
28 words
The method as defined in claim 1 wherein said glutinous waste mass is exposed to a burner flame while maintained out of contact with the combustion chamber wall.
Claim 4
Dependent Claim
23 words
The method as defined in claim 1 wherein said combustion chamber is preheated to a temperature between about 1,200* F. to 1,900* F.
Claim 5
Dependent Claim
64 words
The invention as defined in claim 2 wherein said glutinous mass is rotated in the presence of said combustion chamber heat and said burner flame while maintained out of contact with said combustion chamber wall until said glutinous waste mass is partially incinerated and the temperature is raised sufficiently to preclude the formation of a thermal gradient when deposited on the combustion chamber wall.
Claim 6
Dependent Claim
24 words
The method as defined in claim 4 wherein said glutinous mass is deposited on a metal grate formed by a plurality of spaced arms.
Claim 7
Dependent Claim
41 words
The invention as defined in claim 5 wherein said arms are arranged so that alternate ones are disposed substantially normal to the remaining arms so that said partially incinerated mass may drop between said arms on to the combustion chamber wall.
Claim 8
Dependent Claim
28 words
The invention as defined in claim 6 wherein said partially incinerated waste deposited on the combustion wall is agitated simultaneously with the glutinous mass deposited on said grate.
Claim 9
Dependent Claim
28 words
The invention as defined in claim 4 wherein said glutinous waste is deposited in said combustion chamber at a rate commensurate with the burning rate of said waste.
