Abstract
Abstract Comminuted waste fuel or material is injected into the incinerator at the bottom thereof through a conduit. Centrally arranged in this conduit, at the discharge end thereof is a second auxiliary fuel conduit which is provided at its termination end within the first conduit with a plurality of fuel discharge orifices which are directed radially outwardly and upwardly towards the discharge end of the first conduit. The incinerator also includes provision for a separator wherein the baffles and bottom disc are cooled by means of circulating air which is then discharged from the disc portion of the separator in a tangential direction complementing the direction of rotation of the cyclone within the incinerator.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
161 words
A co-axial burner for use in suspension burning incinerators of the cyclone type to burn comminuted waste material, comprising, an outer comminuted waste and primary air supply conduit and aN inner co-axial auxiliary fuel supply conduit, the inner wall of said outer conduit being spaced apart from the outer wall of the auxiliary fuel supply conduit to thereby define an annular passage and to permit the flow of comminuted waste and primary air therethrough, said outer conduit having an outwardly flared discharge end and said auxiliary fuel supply conduit terminating within said outer conduit proximate the outwardly flared discharge end thereof, said auxiliary fuel supply conduit including at its termination end a burner element provided with a plurality of first fuel discharge orifices wherein said first orifices are circularly arranged and directed radially outwardly and upwardly from said fuel supply conduit towards the discharge end of said outer conduit and said first orifices are in communication with said fuel supply conduit.
Claim 2
Dependent Claim
161 words
A co-axial burner for use in suspension burning incinerators of the cyclone type to burn comminuted waste material, comprising, an outer comminuted waste and primary air supply conduit and aN inner co-axial auxiliary fuel supply conduit, the inner wall of said outer conduit being spaced apart from the outer wall of the auxiliary fuel supply conduit to thereby define an annular passage and to permit the flow of comminuted waste and primary air therethrough, said outer conduit having an outwardly flared discharge end and said auxiliary fuel supply conduit terminating within said outer conduit proximate the outwardly flared discharge end thereof, said auxiliary fuel supply conduit including at its termination end a burner element provided with a plurality of first fuel discharge orifices wherein said first orifices are circularly arranged and directed radially outwardly and upwardly from said fuel supply conduit towards the discharge end of said outer conduit and said first orifices are in communication with said fuel supply conduit.
Claim 3
Dependent Claim

A co-axial burner as claimed in claim 1, wherein said burner element is provided with a plurality of second fuel discharge orifices communicating with a secondary fuel supply conduit internally of said auxiliary fuel supply conduit, said second fuel dicharge orifices being positioned internally of said first fuel discharge orifices and wherein said second orifices are circularly arranged and directed radially outwardly and upwardly from said secondary fuel supply conduit towards the discharge end of said outer conduit.
Claim 4
Dependent Claim
30 words
A co-axial burner as claimed in claim 1, wherein said auxiliary fuel supply conduit at its termination end is provided with an upwardly and outwardly tapering annular and perforated shield.
