Abstract
Abstract An apparatus for reacting finely divided material in a fluidized bed supported by a circular grate in relative circular motion with regard to a cell enclosing an auxiliary bed which has a bottom in free communication with the main fluidized bed and which is in hydrostatic equilibrium with the latter, whereby slag settled on the grate is sorted and extracted.

Claim 1
Independent Claim
183 words
AN APPARATUS FOR REACTING FINELY DIVIDED MATERIALS IN A FLUIDIZED BED AT A TEMPERATURE UNVOLVING SELF-AGGLOMERATING CONDITIONS UNDER WHICH SLAG SINKES GRADUALLY THROUGH SAID FLUIDIZED BED, COMPRISING AN AT LEAST PARTLY CYLINDRICAL REACTOR; A CIRCULAR GATE ELEMENT LOCATED WITHIN SAID REACTOR AND ADAPTED TO CARRY A MAIN FLUIDIZEED BED AND SLAG WHICH SETTLES THROUGH THE SAME ONTO SAID GATE MEMBER, A CELL ELEMENT OVERLYING PORTION OF SAID GATE ELEMENT AND DEFINING WITH THE SAME AN ENCLOSED SPACE WHICH IS OPEN AT THE BOTTOM TO SAID GRATE ELEMENT AND ADAPTED TO ACCOMMODATE AN AUXILIARY SHALLOW FLUIDIZED BED, SAID CELL ELEMENT HAVING A SIDE WALL ORRIENTED SUBSTANTIALLY RADIALLY AND FORMED WITH AN INLET OPENING COMMUNICATING SAID FLUIDIZED BEDS WITH ONE ANOTHER AND THROUGH WHICH SLAG ENTERS SAID SPACE, AND A SUBSTANTIALLY CIRCUMFERENTIAL WND WALL FORMED AN OUTLET OPENING FOR THE SLAG; MEANS FOR IMPARTING TO ONE OF SAID ELEMENTS A CIRCULAR MOTION RELATIVE FOR IMPARTING TO ONE OF SAID ELEMENTS A CIRCULAR MOTION RELATIVE AND SLAG SETTLED ON SAID GRATE ELEMENT ENTER SAID SPACE THROUGH SAID INLET OPENING; AND MEANS FOR BLOWING A REACTING FLUODIZING

Claim 3
Dependent Claim
38 words
An apparatus as defined in claim 1, wherein said grate element rotates in a horizontal plane; and wherein said cell element is stationary and said end wall formed with said outlet opening faces radially outwardly of said reactor.
Claim 4
Dependent Claim
43 words
An apparatus as defined in claim 1, wherein said grate element rotates in an inclined plane; and wherein said cell element is stationary and said outlet opening is located at the highest level of said grate element and faces outwardly of said reactor.
Claim 5
Dependent Claim
63 words
An apparatus as defined in claim 1; further comprising means defining a discharge passage at the center of said reactor; said grate element being annular, surrounding said discharge passage and rotating in a horizontal plane; and wherein said cell element is stationary and said outlet opening faces inwardly of said reactor and communicates with said discharge passage for discharging slag into the same.
Claim 6
Dependent Claim
63 words
An apparatus as defined in claim 1; further comprising means defining a discharge passage at the center of said reactor; said grate element being annular, surrounding said discharge passage and rotating in an inclined plane; and wherein said cell element is stationary and said outlet opening faces inwardly of said reactor and communicates with said discharge passage for discharging slag into the same.
Claim 7
Dependent Claim
70 words
