Abstract
Abstract A method of incinerating toilet waste comprising applying combustion heat in substantially the manner of applying heat to the bottom of a cooking pot under and to and through the bottom of a heat permeable upwardly opening receptacle containing the waste and thereby effecting substantial boiling and incineration of the waste, supplying preheated air into the receptacle, and compelling vapor and products of combustion generated by the combustion heat to pass from the receptacle into a combustion zone under the receptacle and through the combustion heat and into an after burner flue leading from the combustion chamber. An aesthetically desirable and sanitary masking foam may be applied to the surface of accumulated toilet waste in the receptacle prior to boiling and incineration.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
96 words
A method of incinerating toilet waste, comprising: applying combustion heat in substantially the manner of applying heat to the bottom of a cooking pot under and to and through the bottom of a heat permeable upwardly opening receptacle containing the waste and effecting substantial boiling and incineration of the waste; supplying preheated air into said receptacle; and compelling vapor and products of combustion generated by said combustion heat to pass from said receptacle into a combustion zone chamber under said receptacle and through the combustion heat and into an afterburner flue leading from the combustion chamber.
Claim 2
Independent Claim
96 words
A method of incinerating toilet waste, comprising: applying combustion heat in substantially the manner of applying heat to the bottom of a cooking pot under and to and through the bottom of a heat permeable upwardly opening receptacle containing the waste and effecting substantial boiling and incineration of the waste; supplying preheated air into said receptacle; and compelling vapor and products of combustion generated by said combustion heat to pass from said receptacle into a combustion zone chamber under said receptacle and through the combustion heat and into an afterburner flue leading from the combustion chamber.
Claim 3
Dependent Claim
32 words
A method according to claim 1, including applying said combustion heat by flame from an array of atmospheric gas burner orifices, and passing the vapor and products of combustion through the flames.
Claim 4
Dependent Claim
31 words
A method according to claim 1, comprising effecting incandescent heating of a stack defining the afterburner flue and thereby assuring total conversion of vapor and products of combustion to innocuous gas.
Claim 5
Dependent Claim
21 words
A method according to claim 1, including supplying additional combustion promoting air into the combustion chamber adjacent to the afterburner flue.
Claim 6
Dependent Claim
34 words
A method according to claim 1, wherein said afterburner flue extends vertically, and effecting cooling of an upper end portion of the flue and mixing cooling air with flue gases discharged from the flue.
Claim 7
Dependent Claim
49 words
A method according to claim 1, comprising supplying primary combustion air and gas to provide said combustion heat, supplying said preheated air as secondary combustion air, and supplying tertiary combustion air into the combustion chamber adjacent to passage of the vapor and products of combustion into the afterburner flue.
Claim 8
Dependent Claim
60 words
A method according to claim 1, comprising boiling the toilet waste in the receptacle for a substantial period of time in a vapor driving off phase during incineration and thereby breaking down solids in the waste into a slurry to promote combustion of the solids in the receptacle when the solids have dried out from application of the combustion heat.
Claim 9
Dependent Claim
41 words
A method according to claim 1, comprising prior to applying the combustion heat under the receptacle accumulating a large volume of toilet waste in the receptacle, and applying to the waste in the receptacle an aesthetically desirable and sanitary masking foam.
Claim 10
Dependent Claim
52 words
A method according to claim 1, comprising directly exposing to the interior of the combustion zone chamber substantially enclosing lightweight high melting point ceramic fiber refractory material, and in the afterburner flue directly exposing lightweight high melting point ceramic fiber refractory material to a passage defined by a stack in said flue.
Claim 11
Dependent Claim
70 words
A method according to claim 1, comprising lining the combustion zone chamber with high melting point fibrous ceramic insulation having relatively rough surfaces directly exposed to the combustion zone chamber, heating said surfaces to incandescence, subjecting the vapor and products of combustion passing through the combustion zone chamber to incandescent radiation, and effecting turbulence of the products of combustion and vapor at the boundary layer of the rough incandescing surfaces.
