Abstract
Abstract A system is disclosed for incinerating fluid (liquid and/or gas) and solid waste including a first, second, and third combustion zones of successively larger interior volumes. Liquid wastes are introduced into the first combustion zone and solid wastes are introduced into the third combustion zone, whereby solid wastes are heated from conduction and/or convection by the first and/or the second combustion zone prior to the solid wastes being introduced into the third combustion zone.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
172 words
A system for incinerating fluid and solid waste, comprising: a first combustion zone having an inlet for the introduction of fluid waste through a burner system and an outlet, a second combustion zone of a larger interior volume and diameter than the first combustion zone, the second combustion zone having an inlet for the introduction of emissions from the first combustion zone's outlet and an outlet, a third combustion zone of a larger interior volume and diameter than the second combustion zone, the third combustion zone having a first inlet for the introduction of emissions from the second combustion zone's outlet, a second inlet adjacent the first inlet for the introduction of solid waste, and an outlet opposite from the first and second inlets for discharge of gaseous and solid emissions, and means for introducing solid waste through the third combustion zone's second inlet, a portion of the introduction means being adapted to heat any solid waste therein from conduction and/or convection heat developed from the first and/or the second combustion zones.
Claim 2
Independent Claim
172 words
A system for incinerating fluid and solid waste, comprising: a first combustion zone having an inlet for the introduction of fluid waste through a burner system and an outlet, a second combustion zone of a larger interior volume and diameter than the first combustion zone, the second combustion zone having an inlet for the introduction of emissions from the first combustion zone's outlet and an outlet, a third combustion zone of a larger interior volume and diameter than the second combustion zone, the third combustion zone having a first inlet for the introduction of emissions from the second combustion zone's outlet, a second inlet adjacent the first inlet for the introduction of solid waste, and an outlet opposite from the first and second inlets for discharge of gaseous and solid emissions, and means for introducing solid waste through the third combustion zone's second inlet, a portion of the introduction means being adapted to heat any solid waste therein from conduction and/or convection heat developed from the first and/or the second combustion zones.
Claim 3
Dependent Claim
20 words
The system of claim 1 wherein the second combustion zone includes an inlet for introduction of liquid and/or gaseous waste.
Claim 4
Dependent Claim
14 words
The system of claim 1 wherein the third combustion zone is a rotary kiln.
Claim 5
Dependent Claim
21 words
The system of claim 1 and including a post combustion chamber in communication with the outlet of the third combustion zone.
Claim 6
Dependent Claim
28 words
The system of claim 4 and including means for recycling a portion of the gaseous products of combustion from the post combustion chamber into the second combustion zone.
Claim 7
Dependent Claim
15 words
The system of claim 1 wherein the second combustion zone includes a plurality of nozzles.
Claim 8
Dependent Claim
23 words
The system of claim 1 wherein the introduction means comprises a conduit spaced adjacent to a lower portion of the second combustion zone.
Claim 9
Dependent Claim
26 words
The system of claim 7 and including plunger means for forcing solid waste through the conduit and into a lower portion of the third combustion zone.
Claim 10
Dependent Claim
56 words
The system of claim 6 wherein the second combustion zone comprises a circular wall member having a horizontal baffle dividing the wall member into two zones, the upper zone being for combustion of the liquid and/or gaseous waste, and the lower zone being the conduit for introduction of preheated solid waste into the third combustion zone.
Claim 11
Dependent Claim
20 words
The system of claim 1 wherein the second combustion zone includes fluid introduction means for controlling the temperature of combustion.
Claim 12
Dependent Claim
41 words
The system of claim 1 and including forced air sealing means between the second and the third combustion zones to pass air into the interior of the third combustion zones parallel with the flow of gases in the third combustion zone.
