Abstract
Abstract A novel thermal reactor or incinerator of a fluidized bed type is provided wherein residua which have descended to the bottom of the fluidizing bed are transferred to a discharge opening by a plurality of hollow cylindrical rotors disposed above the bottom plate of a vessel of the reactor or incinerator, each of the rotors being provided with a plurality of perforations in the cylindrical wall through which gas or air is injected into inert solid or sand particles to form the fluidized bed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
92 words
A thermal reactor of a fluidized bed type comprising: a vessel including a bottom plate provided with a discharge opening; A plurality of hollow cylindrical rotors disposed in parallel above said bottom plate with a predetermined space between the adjacent rotors, each of the rotors being provided with a plurality of gas injecting perforations in the cylindrical wall thereof with the inside space of the rotor being coupled with a gas source, all the rotors being arranged to rotate in the same direction; and a feeder for supplying materials into the vessel.
Claim 2
Dependent Claim
92 words
A thermal reactor of a fluidized bed type comprising: a vessel including a bottom plate provided with a discharge opening; A plurality of hollow cylindrical rotors disposed in parallel above said bottom plate with a predetermined space between the adjacent rotors, each of the rotors being provided with a plurality of gas injecting perforations in the cylindrical wall thereof with the inside space of the rotor being coupled with a gas source, all the rotors being arranged to rotate in the same direction; and a feeder for supplying materials into the vessel.
Claim 3
Dependent Claim
21 words
A thermal reactor as claimed in claim 1 wherein said bottom plate is provided with a plurality of gas injecting perforations.
Claim 4
Dependent Claim
33 words
A thermal reactor as claimed in claim 2 wherein said perforations in the bottom plate are arranged so that the injection gas flow therethrough has a component vector directed towards said discharge opening.
Claim 5
Dependent Claim
25 words
A thermal reactor as claimed in any one of claims 1, 2 or 3 wherein said bottom plate is inclined downwardly towards said discharge opening.
Claim 6
Dependent Claim
40 words
A thermal reactor as claimed in any one of claims 1, 2 or 3 wherein the gap between the bottom plate and the rotors is arranged to be greater than the gap between the adjacent rotors in said predetermined space.
Claim 7
Dependent Claim
34 words
A thermal reactor as claimed in claim 4 wherein the gap between the bottom plate and the rotors is arranged to be greater than the gap between the adjacent rotors in said predetermined space.
