Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
94 words
An apparatus for incinerating solids entrained in a fluid such as sewage sludge and the like comprising a chamber having a flue, baffle means mounted in said chamber, means for injecting a stream of high velocity air into said chamber so that the stream of air impinges substantially perpendicularly upon said baffle means, to produce a zone of turbulent air, means for heating said air injected into said chamber to produce a zone of heated turbulent air and means for injecting said solids entrained in a fluid into said zone of heated turbulent air.
Claim 2
Independent Claim
94 words
An apparatus for incinerating solids entrained in a fluid such as sewage sludge and the like comprising a chamber having a flue, baffle means mounted in said chamber, means for injecting a stream of high velocity air into said chamber so that the stream of air impinges substantially perpendicularly upon said baffle means, to produce a zone of turbulent air, means for heating said air injected into said chamber to produce a zone of heated turbulent air and means for injecting said solids entrained in a fluid into said zone of heated turbulent air.
Claim 3
Dependent Claim
22 words
An apparatus according to claim 1, wherein said baffle means is provided with a concave surface upon which said injected air impinges.
Claim 4
Dependent Claim
30 words
An apparatus according to claim 1, wherein said means for injecting said solids entrained in a fluid into said zone of heated turbulent air is mounted in said baffle means.
Claim 5
Dependent Claim
24 words
An apparatus according to claim 1, wherein said baffle means is disposed between said means for injecting air into said chamber and said flue.
Claim 6
Dependent Claim
33 words
An apparatus according to claim 1, wherein said means for injecting said solids entrained in a fluid into said chamber is disposed in heat transfer relation with heated gases discharged through said flue.
Claim 7
Dependent Claim
63 words
An apparatus according to claim 1, wherein said baffle means is disposed between said means for injecting air into said chamber and said flue, said baffle means is provided with a concave surface upon which said injected air impinges and said means for injecting said solids entrained in a fluid into said zone of heated turbulent air is mounted in said baffle means.
Claim 8
Dependent Claim
49 words
