Abstract

Abstract An incinerator for combustible materials utilizes direct heating distillation to convert the material to a gaseous state after which the gaseous material is directed upwardly past a heat source which functions as an afterburner. A first chamber receives the combustible material while a second chamber disposed above the first chamber houses the heat source. The heat source raises the temperature in the first chamber to achieve conversion of the material to a gaseous state either by partial combustion or vaporization. An aspirator tube located immediately beneath the heat source creates an area of negative pressure which draws the gaseous material upwardly into the second chamber. In the second chamber essentially complete combustion of the gaseous material takes place. The first chamber has an open bottom and is movable vertically upon the pressure within the first chamber exceeding the design maximum. This minimizes any danger of damage from explosion by allowing any excess pressure to be relieved through the open bottom. The combustible material is contained by a basket in the first chamber which basket is mounted on rollers and is movable along a track to and from the interior of the chamber.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 187 words
Apparatus for the Combustion of a material capable of conversion to a gaseous state upon the application of heat, said apparatus comprising: a first lower chamber for receiving the combustible material, said first lower chamber being free of any source of fuel which would support combustion of the material in the lower chamber; a second upper chamber disposed above and in communication with said lower chamber and having a horizontal cross-sectional area of between one-seventh and one-twelfth of the corresponding area of the lower chamber; burner means disposed in said second chamber at an angle of between 0* and 45* relative to the horizontal for raising the temperature in said first lower chamber to achieve conversion of said material to a gaseous state; deflection structure disposed in said upper chamber for deflecting heat currents from the burner means down into said first chamber; and means for creating an upward draft in said first chamber to move the gases upwardly into said second chamber and past said burner means whereby complete combustion of the material occurs when the material is in a gaseous state in said second chamber.
Claim 2
Dependent Claim 187 words
Apparatus for the Combustion of a material capable of conversion to a gaseous state upon the application of heat, said apparatus comprising: a first lower chamber for receiving the combustible material, said first lower chamber being free of any source of fuel which would support combustion of the material in the lower chamber; a second upper chamber disposed above and in communication with said lower chamber and having a horizontal cross-sectional area of between one-seventh and one-twelfth of the corresponding area of the lower chamber; burner means disposed in said second chamber at an angle of between 0* and 45* relative to the horizontal for raising the temperature in said first lower chamber to achieve conversion of said material to a gaseous state; deflection structure disposed in said upper chamber for deflecting heat currents from the burner means down into said first chamber; and means for creating an upward draft in said first chamber to move the gases upwardly into said second chamber and past said burner means whereby complete combustion of the material occurs when the material is in a gaseous state in said second chamber.
Claim 3
Dependent Claim 42 words
Apparatus as set forth in claim 1, wherein said first chamber is provided with an open bottom and is movable vertically upon the pressure within the first chamber exceeding the design maximum whereby the excess pressure is relieved through said open bottom.
Claim 4
Dependent Claim 42 words
Apparatus as set forth in claim 1, wherein said draft creating means comprises an aspirator tube disposed beneath said burner means and having its outlet directed toward the heating means for creating an area of negative pressure immediately beneath said heating means.
Claim 5
Dependent Claim 22 words
Apparatus as set forth in claim 3, wherein is included means for delivering an auxiliary supply of air to the burner means.
Claim 6
Dependent Claim 34 words
Apparatus as set forth in claim 1, wherein said second chamber extends above said heating means to provide a stack for delivery of the products of combustion of the gaseous materials to the atmosphere.
Claim 7
Dependent Claim 68 words
Apparatus as set forth in claim 1, wherein is included blower means for providing said auxiliary air supply; a shroud in spaced relationship to and surrounding said first chamber; and means for coupling the area between the shroud and the first chamber to the intake of said blower means whereby air is circulated around said first chamber to cool the latter when the blower means is in operation.
Claim 8
Dependent Claim 27 words
Apparatus as set forth in claim 6, wherein said aspirator tube is coupled with the output of said blower means for creating said area of negative pressure.
Claim 9
Dependent Claim 28 words
Apparatus as set forth in claim 7, wherein is included a basket movable to and from said first chamber for holding said combustible material in the first chamber.
Claim 10
Dependent Claim 73 words
Apparatus as set forth in claim 8, wherein said shroud and said first chamber are provided with an access door to the inside of said first chamber, said basket is provided with a plurality of rollers disposed in supporting relationship thereto; and including a track extending into said first chamber from the outside whereby said basket can be rolled in and out of said first chamber along the track and through said door.
Claim 11
Dependent Claim 27 words
Apparatus as set forth in claim 1, wherein said draft creating means comprises means for introducing a flow of air into said first chamber beneath said material.
Claim 12
Dependent Claim 28 words
Apparatus as set forth in claim 1, wherein said second chamber includes a frustoconical section adjacent said first chamber, and said heating means is disposed in said section.
Claim 13
Dependent Claim 29 words
Apparatus as set forth in claim 11, wherein said section provides for the introduction of air into the second chamber in parallel relationship to the sidewalls of said section.
Claim 14
Dependent Claim 28 words
Apparatus as set forth in claim 12, wherein said section comprises a plurality of nonaligned frustoconical elements disposed in spaced relationship to allow the passage of air therebetween.
Claim 15
Dependent Claim 44 words
Apparatus as set forth in claim 1, wherein said second chamber includes a plurality Of baffles disposed therein in spaced relationship to allow the passage of air therebetween, said baffles extending into the interior of said second chamber to promote distribution of air therein.
