Abstract

Abstract An incinerator for burning waste material having a combustion chamber comprising spaced end walls and a side wall through which a mixture of waste material and air is vortically moved and burned. The incinerator combustion chamber includes a tangentially directed inlet conduit means for feeding a mixture of waste material and air under pressure from a blower into the chamber, and an exhaust flue to vent combustion gases from the chamber. The inlet conduit means is provided with a valve means intermediate the combustion chamber and blower for closing off the conduit when the blower is not operational, and means are provided for introducing cooling air to said valve means in the inlet conduit.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 110 words
An incinerator for burning waste material comprising in combination: a) a combustion chamber having spaced end walls and a side wall with its central longitudinal axis extending between said end walls; b) inlet conduit for introducing waste material and air into said combustion chamber in a manner effective for providing a vortical movement of said waste material toward one of said end walls, said inlet conduit having valve means therein for closing off and opening passage through the inlet conduit and means for introducing cooling air into said inlet conduit in the region of the said valve means; and c) means for igniting said waste material during its vortical movement.
Claim 2
Dependent Claim 110 words
An incinerator for burning waste material comprising in combination: a) a combustion chamber having spaced end walls and a side wall with its central longitudinal axis extending between said end walls; b) inlet conduit for introducing waste material and air into said combustion chamber in a manner effective for providing a vortical movement of said waste material toward one of said end walls, said inlet conduit having valve means therein for closing off and opening passage through the inlet conduit and means for introducing cooling air into said inlet conduit in the region of the said valve means; and c) means for igniting said waste material during its vortical movement.
Claim 3
Dependent Claim 67 words
The incinerator as defined in claim 1, wherein said means for introducing cooling air into said inlet conduit comprises an air duct supplied from a source of air and which is located to direct its discharging stream of cooling air into said inlet conduit adjacent to the surface of the valve means facing the combustion chamber to cool said valve surface and protect it from heat distortion.
Claim 4
Dependent Claim 33 words
The incinerator as defined in claim 1, having means to open and close the said valve means within the inlet conduit, and to regulate the introduction of cooling air into said inlet conduit.
Claim 5
Dependent Claim 73 words
The incinerator as defined in claim 1, having size-reducing means for reducing the size of the waste material and a blower means communicating with said inlet conduit for entraining the size-reduced waste material in air and thus conveying it through the inlet conduit into the combustion chamber, and said valve means for closing off and opening the inlet conduit being located within the inlet conduit between the blower means and the combustion chamber.
Claim 6
Dependent Claim 83 words
The incinerator as defined in claim 4, having an actuator means connected to said valve means within the inlet conduit to open and close said valve, said actuator means being in operative contact with the said blower means communicating with the inlet conduit whereby said acutator means closes the valve means to terminate passage through the inlet conduit when the blower means is not operating and opens the valve means to permit passage through the inlet conduit when the blower means is operating.
Claim 7
Dependent Claim 143 words
The incinerator as defined in claim 5, having means for introducing cooling air into said inlet conduit comprising an air duct supplied from a source of cooling air and which is located to direct a discharge stream of cooling air into said inlet conduit adjecent to the surface of the valve means in the inlet conduit facing the combustion chamber, and said air duct being provided with a valve to regulate the introduction of cooling air into said inlet conduit and actuating means for said valve in operative communication with the blower means whereby said actuator means operates the valve in the cooling air duct to permit cooling air to be introduced into the inlet conduit adjacent the said surface of the valve means therein when the blower means is not operating and the said valve means is closing off the inlet conduit.
Claim 8
Dependent Claim 76 words
The incinerator as defined in claim 6, wherein said valve means in the inlet conduit comprises a pivotal valve member which seats transversely abutting against a terminal end in a section of the inlet conduit when in closed position thereby obstructing passage through said inlet conduit, and which pivots away from its seaT on said terminal end of the inlet conduit section in open position to permit passage through the inlet conduit to the combustion chamber.
Claim 9
Dependent Claim 88 words
The incinerator as defined in claim 7, wherein said valve means is contained within a housing comprising an enlarged section of the inlet conduit which is in communication with said terminal end in the section of the inlet conduit when the valve means is in open position, and the said cooling air duct is connected with the enlarged section of the inlet conduit adjacent to the pivotal valve member whereby the stream of cooling air from the duct is directed over the surface of the said valve member.
Claim 10
Dependent Claim 46 words
The incinerator as defined in claim 8, wherein said valve member pivots in an arc of at least about 90* between its closed and fully open position on a rotatable shaft which is mounted on said enlarged section of the inlet conduit comprising the valve housing.
Claim 11
Dependent Claim 127 words
The incinerator as defined in claim 9, wherein the valve member is secured in fixed relation to the said rotatable shaft and said shaft is rotatably connected to an actuating means which is controlled by the operation of the blower means whereby the said actuator means rotates the shaft to pivot the valve member to open position when the blower is in operation and rotates the shaft to pivot the valve member to closed position seated transversely abutting over the terminal end of the section of inlet conduit connected to the said blower means when the blower is not operating whereby the pivoted valve functions as a check valve and in its closed position provides positive blockage preventing blow back from the combustion chamber to the blower.
