Abstract
Abstract A system including conduit connected to a source of solid waste, a shredder for particlizing solid waste, an igniter for igniting particlized waste, a gas burner for initially heating the liner of the igniter to a temperature above ignition temperatures for the waste, and an air duct for transporting burning particles of waste along a vortexing path extending downwardly through the igniter, then through an agitating conduit, within which the burning particles are maintained in suspension and are finally introduced upwardly into a particle trap within which combustion of ignited particles is completed. A by-products recovery system is connected with the trap for collecting ash, for subsequent usage, and for recovering heat to be returned to the gin.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
155 words
In a method for incinerating combustible gin waste, the steps of: A. particlizing gin waste to form particles of substantially uniform size; B. mixing said particles in a first flowing stream of atmospheric air; C. igniting said particles by causing said particles to frictionally engage a surface of an ignition chamber heated to a temperature sufficient to ignite the particles in response to the engagement thereof with the surface in the presence of the atmospheric air; D. suspending the ignited particles in a second stream of combustion-supporting air and downwardly expelling the second stream from the ignition chamber and thereafter conveying the ignited particles suspended in said second stream to a combustion chamber along a further path segment sufficiently turbulent to assure continued combustion of the ignited particles as they are conveyed from the ignition chamber to a combustion chamber; and E. entrapping the ignited particles in the combustion chamber until the particles are consumed.
Claim 2
Dependent Claim
155 words
In a method for incinerating combustible gin waste, the steps of: A. particlizing gin waste to form particles of substantially uniform size; B. mixing said particles in a first flowing stream of atmospheric air; C. igniting said particles by causing said particles to frictionally engage a surface of an ignition chamber heated to a temperature sufficient to ignite the particles in response to the engagement thereof with the surface in the presence of the atmospheric air; D. suspending the ignited particles in a second stream of combustion-supporting air and downwardly expelling the second stream from the ignition chamber and thereafter conveying the ignited particles suspended in said second stream to a combustion chamber along a further path segment sufficiently turbulent to assure continued combustion of the ignited particles as they are conveyed from the ignition chamber to a combustion chamber; and E. entrapping the ignited particles in the combustion chamber until the particles are consumed.
Claim 3
Independent Claim
160 words
A method of disposing of combustible waste comprising the steps of: A. mixing particles of waste with a first flowing stream of combustion-supporting air and introducing the stream into an ignition chamber; B. propelling the particles in the first stream of combustion-supporting air along a descending spiraled path segment in frictional engagement with a curved ignition surface heated to a temperature sufficient to initiate combustion of said particles for thereby igniting the particles; C. suspending the ignited particles in a second stream of combustion-supporting air and downwardly expelling the second stream from the ignition chamber and thereafter conveying the expelled particles suspended in said second stream to a combustion chamber along a further path segment sufficiently tortuous for establishing within the second stream turbulence sufficient to assure continued combustion of the ignited particles as they are conveyed from the ignition chamber to a combustion chamber; and D. entrapping the ignited particles in the combustion chamber until the particles are consumed.
Claim 4
Independent Claim
160 words
A method of disposing of combustible waste comprising the steps of: A. mixing particles of waste with a first flowing stream of combustion-supporting air and introducing the stream into an ignition chamber; B. propelling the particles in the first stream of combustion-supporting air along a descending spiraled path segment in frictional engagement with a curved ignition surface heated to a temperature sufficient to initiate combustion of said particles for thereby igniting the particles; C. suspending the ignited particles in a second stream of combustion-supporting air and downwardly expelling the second stream from the ignition chamber and thereafter conveying the expelled particles suspended in said second stream to a combustion chamber along a further path segment sufficiently tortuous for establishing within the second stream turbulence sufficient to assure continued combustion of the ignited particles as they are conveyed from the ignition chamber to a combustion chamber; and D. entrapping the ignited particles in the combustion chamber until the particles are consumed.
Claim 5
Dependent Claim
38 words
The method as defined in claim 2 wherein the step of entrapping ignited particles in said combustion chamber includes the steps of capturing a body of ignited particles and percolating upwardly therethrough said second stream of combustion-supporting air.
Claim 6
Dependent Claim
24 words
The method of claim 3 further comprising the step of transferring heat from said stream of heated gases to a stream of cooler gases.
Claim 7
Dependent Claim
34 words
The method of claim 3 wherein a further path segment includes angularly related linear segments and said particles are caused to advance therealong for assuring a continuous mixing of the particles in said stream.
Claim 8
Dependent Claim
17 words
The method of claim 4 further comprising the step of shredding waste to form particles of waste.
