Incinerator wall and door structure

Claim 2

An appliance comprising a burning compartment surrounded by a jacket, said jacket having air circulation passages therein, a door in said jacket communicating with the interior of the burning compartment, said door having an air circulation passage therein, port means cooperatively interconnecting the air circulation passages in the door and jacket, means for circulating air within the interior of the burning compartment at a known pressure, and means for circulating cooling air through said air circulation passages in the door and jacket at a pressure slightly greater than the pressure of the air within the burning compartment.

Claim 3

An appliance comprising a burning compartment surrounded by an enclosure, an opening in said enclosure, a frame supported in said enclosure and outlining said opening, a door removably positioned in said frame in closing relation to said opening, and sealing means between said door and frame, said sealing means comprising a pair of spaced resilient O-ring members, one of said sealing members being located inwardly of the other and effectively nearer the burning compartment, the outer of said sealing members being substantially resistant to passage of air therethrough, and the inner sealing member being porous.

Claim 4

An appliance comprising a burning compartment surrounded by an enclosure, an opening in said enclosure, a frame supported in said enclosure and outlining said opening, a door removably positioned in said frame in closing relation to said opening, and sealing means between said door and frame, said sealing means comprising a pair of spaced resilient O-ring members, one of said sealing members being located inwardly of the other and effectively nearer the burning compartment, the outer of said sealing members being substantially resistant to passage of air therethrough, and the inner sealing member being porous.

Claim 5

An appliance as set forth in claim 2 wherein the outer of said sealing members is rubber or plastic, and the inner sealing member is fiber glass braid.

Claim 6

An appliance comprising a burning compartment surrounded by an enclosure, said enclosure comprising walls having air circulation passages therein, an opening in said enclosure for communication with the interior of said burning compartment, a frame supported by said enclosure and outlining said opening, a door removably positioned in closing relation to said opening, said door comprises a front panel and a rear panel and having an air circulation passage disposed between said panels, said rear panel extends across said opening, said frame has a substantially planar portion extending around said opening in overlying and substantially parallel relation to said rear panel, sealing means between said door and said frame comprising a pair of spaced resilient O-ring members, one of said sealing members is located inwardly of the other and effectively nearer the burning compartment, the outer sealing member is substantially resistant to passage of air therethrough, said inner sealing member is porous, port means cooperatively interconnecting the air circulation passages in the door and enclosure walls via the space between said members, and means for circulating cooling air through said air circulation passages in the door and walls.

Claim 7

An appliance comprising a burning compartment surrounded by an enclosure, said enclosure comprising walls having air circulation passages therein, an opening in said enclosure for communication with the interior of said burning compartment, a frame supported by said enclosure and outlining said opening, a door removably positioned in closing relation to said opening, said door comprises a front panel and a rear panel and having an air circulation passage disposed between said panels, said rear panel extends across said opening, said frame has a substantially planar portion extending around said opening in overlying and substantially parallel relation to said rear panel, sealing means between said door and said frame comprising a pair of spaced resilient O-ring members, one of said sealing members is located inwardly of the other and effectively nearer the burning compartment, the outer sealing member is substantially resistant to passage of air therethrough, said inner sealing member is porous, port means cooperatively interconnecting the air circulation passages in the door and enclosure walls via the space between said members, and means for circulating cooling air through said air circulation passages in the door and walls.

Claim 8

An appliance as set forth in claim 4 wherein said air circulating means includes means for also directing air into the interior of the burning compartment at a known pressure, and means for directing said cooling air through said walls and door at a pressure slightly greater than the pressure within the burning compartment.

Claim 9

An appliance comprising a burning compartment surrounded by an enclosure, said enclosure having spaced inner and outer walls defining an air passage therebetween, an opening in said enclosure communicating with the interior of the burning compartment, a door removably positioned in closing relation to said opening, said door comprising front and rear panels defining an air passage therebetween, ports cooperatively interconnecting the air passages in the walls and door, means for circulating air through said burning compartment at a known pressure, and means for circulating cooling air through said wall and door passages via said ports at a pressure slightly greater than the pressure of the air within the burning compartment.

Claim 10

An appliance comprising a burning compartment surrounded by an enclosure, said enclosure having spaced inner and outer walls defining an air passage therebetween, an opening in said enclosure communicating with the interior of the burning compartment, a door removably positioned in closing relation to said opening, said door comprising front and rear panels defining an air passage therebetween, ports cooperatively interconnecting the air passages in the walls and door, means for circulating air through said burning compartment at a known pressure, and means for circulating cooling air through said wall and door passages via said ports at a pressure slightly greater than the pressure of the air within the burning compartment.

Claim 11

An appliance as set forth in claim 6 wherein a pair of spaced inner and outer O-ring seals are disposed between the door and surrounding wall of the enclosure, and said inner seal is porous whereby some of the air flowing from said passage in the wall toward said passage in the door will percolate into the burning compartment.

Claim 12

An appliance as set forth in claim 1 wherein sealing means is provided between said door and jacket comprising an outer substantially nonporous member, and an inner member which is porous to the higher pressure air within the jacket and door.
