Abstract
Abstract An incinerator for burning waste material such as garbage, trash and the like which includes a furnace having an interior and an inlet opening in the furnace side wall through which finely divided waste material is introduced from one end of an elongated trough provided with a plurality of comminuting rolls for grinding and cutting waste material introduced into the other end of the trough and for conveying the waste material through the trough and into the furnace. The furnace inlet opening is provided with a closure and an air spray device which in the open position of the closure distributes the comminuted waste material throughout the furnace interior while simultaneously providing a substitute closure for the inlet opening. The gaseous products of combustion are conducted from the furnace through a stack into which wash water is introduced for removal of the solids.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
262 words
An incinerator comprising, in combination, a furnace having a side wall, a top wall and a bottom wall defining an interior for accommodating waste material to be burned, means for introducing fuel into said furnace interior, a tubular stack connected to said furnace top wall in communication with said furnace interior for removing gaseous combustion products from said furnace interior, means for introducing a spray of water into said stack for washing solids from said gaseous combustion products flowing in said stack, means for conducting said wash water from said stack, an accEss opening in said furnace side wall adjacent said furnace bottom wall for removal of ashes from said furnace interior, an inlet opening in said furnace side wall intermediate said furnace top and bottom walls for introduction of said waste material to be burned into said furnace interior, an elongated trough having a top wall, a bottom wall, a pair of side walls, an inlet end and an outlet end connected in communication with said furnace inlet opening, a plurality of transversely extending, longitudinally spaced comminuting rolls disposed in said trough for converting said waste material introduced into said trough inlet end into particulate form and for conducting waste material from said trough inlet end into the interior of said furnace through said furnace inlet opening, means associated with each of said rolls for rotating the associated roll at a selected speed, a closure for said furnace inlet opening movable between a closed position and an open position to permit the introduction of said waste material into said furnace interior.
Claim 2
Dependent Claim
262 words
An incinerator comprising, in combination, a furnace having a side wall, a top wall and a bottom wall defining an interior for accommodating waste material to be burned, means for introducing fuel into said furnace interior, a tubular stack connected to said furnace top wall in communication with said furnace interior for removing gaseous combustion products from said furnace interior, means for introducing a spray of water into said stack for washing solids from said gaseous combustion products flowing in said stack, means for conducting said wash water from said stack, an accEss opening in said furnace side wall adjacent said furnace bottom wall for removal of ashes from said furnace interior, an inlet opening in said furnace side wall intermediate said furnace top and bottom walls for introduction of said waste material to be burned into said furnace interior, an elongated trough having a top wall, a bottom wall, a pair of side walls, an inlet end and an outlet end connected in communication with said furnace inlet opening, a plurality of transversely extending, longitudinally spaced comminuting rolls disposed in said trough for converting said waste material introduced into said trough inlet end into particulate form and for conducting waste material from said trough inlet end into the interior of said furnace through said furnace inlet opening, means associated with each of said rolls for rotating the associated roll at a selected speed, a closure for said furnace inlet opening movable between a closed position and an open position to permit the introduction of said waste material into said furnace interior.
Claim 3
Dependent Claim
85 words
An incinerator in accordance with claim 1 including air spray means operatively associated with said closure movable between an inoperative position in the closed position of said closure and an operative position in the open position of said closure to direct a spray of air into said furnace interior throughout the marginal edges of said inlet opening for distribution of said particulate waste material throughout said furnace interior and to provide an air seal for said inlet opening in the open position of said closure.
Claim 4
Dependent Claim
107 words
An incinerator in accordance with claim 1 including a separation tank having an interior for separating the solids from the water in said wash water, a partition in said tank interior having an upper edge and defining with the walls of said tank a settling portion and a clear water portion, means for communicating said wash water conducting means with the settling portion of said tank, means on said tank for removing the solids from said tank settling portion and means for removing the water from said tank clear water portion and means for controlling the level of said clear water in said clear water tank portion.
Claim 5
Dependent Claim
83 words
An incinerator in accordance with claim 1 wherein said comminuting rolls include a crusher roll disposed adjacent said trough inlet end, said crusher roll including a cylindrical body and a plurality of circumferentially spaced rows of radially projecting lugs on the peripheral surface of said cylindrical body, said lugs in each of said rows being positioned in longitudinally spaced relationship for performing a crushing operation on said waste material and for conveying said waste material to the adjacent comminuting roll in said trough.
Claim 6
Dependent Claim
76 words
An incinerator in accordance with claim 4 wherein said comminuting rolls including a pair of cutter rolls each having a cylindrical body and a plurality of circumferentially spaced, longitudinally extending, radially projecting blades on the peripheral surface of said cylindrical body for performing a comminuting operation on the waste material conveyed by said crusher roll and for conveying said comminuted waste material through said inlet opening into the interior of said furnace at a high velocity.
Claim 7
Dependent Claim
53 words
An incinerator in accordance with claim 5 including means supported on said furnace side wall for introducing air at a high velocity into said furnace interior during combustion of said waste material and means supported on said furnace side wall for introducing oxygen into said furnace interior during combustion of said waste material.
Claim 8
Dependent Claim
35 words
An incinerator in accordance with claim 5 including damper means in said stack for limiting the flow of said gaseous combustion products in said stack to control the pressure in the interior of said furnace.
Claim 9
Dependent Claim
41 words
An incinerator in accordance with claim 5 wherein said top wall is removably positioned on said trough, said top wall being formed in a plurality of sections, each of said trough sections being operatively asSociated with one of said comminuting rolls.
