Abstract
Abstract An apparatus for gas treating a particle bed wherein a uniform temperature gradient is achieved. A support member, such as a grate, serves to support a bed of particles on a surface thereof. The support member is moved in a predetermined direction. Gas is released from a plurality of positions at different depths in the bed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
186 words
An apparatus for gas treating a bed of solid particles comprising: a support member having a surface for supporting the bed of particles thereon; means for moving said support member in a generally horizontal direction; at least one conduit having a longitudinal axis generally perpendicular to said direction, wherein at least a portion of said conduit has a sidewall having a plurality of holes therethrough which are located at a plurality of different distances from said support member surface, distance being measured along lines generally normal to said direction, wherein said conduit portion has a lower end positioned above and closely adjacent to said support member surface, and wherein for first and second longitudinally separated sections of said conduit portion, said second section being closest to said conduit end, the second section includes a greater number of holes than the first section; a means for passing a gas through said at least one conduit so that gas is released from said holes; whereby the bed of particles can be moved in said direction while gas is released in the bed at a plurality of depths therein.
Claim 2
Independent Claim
186 words
An apparatus for gas treating a bed of solid particles comprising: a support member having a surface for supporting the bed of particles thereon; means for moving said support member in a generally horizontal direction; at least one conduit having a longitudinal axis generally perpendicular to said direction, wherein at least a portion of said conduit has a sidewall having a plurality of holes therethrough which are located at a plurality of different distances from said support member surface, distance being measured along lines generally normal to said direction, wherein said conduit portion has a lower end positioned above and closely adjacent to said support member surface, and wherein for first and second longitudinally separated sections of said conduit portion, said second section being closest to said conduit end, the second section includes a greater number of holes than the first section; a means for passing a gas through said at least one conduit so that gas is released from said holes; whereby the bed of particles can be moved in said direction while gas is released in the bed at a plurality of depths therein.
Claim 3
Dependent Claim
32 words
An apparatus as recited in claim 1, wherein said at least one conduit comprises a plurality of conduits, each conduit having at least a portion which has a sidewall with holes therein.
Claim 4
Dependent Claim
14 words
An apparatus as recited in claim 2, wherein said support member is a grate.
Claim 5
Independent Claim
124 words
An apparatus for treating a bed of solid particles comprising: a support member having a surface for supporting the bed thereon; means for moving said support member in a generally horizontal direction; a plurality of conduits, wherein each conduit has an open end positioned closely adjacent to said support member surface and wherein said open ends are located at a plurality of different distances from said support member surface, distance being measured along lines generally normal to said direction; and means for passing a gas through said conduits so that gas is released from said open ends of said conduits; whereby the bed of particles can be moved in said direction while gas is released in the bed at a plurality of depths therein.
Claim 6
Independent Claim
124 words
An apparatus for treating a bed of solid particles comprising: a support member having a surface for supporting the bed thereon; means for moving said support member in a generally horizontal direction; a plurality of conduits, wherein each conduit has an open end positioned closely adjacent to said support member surface and wherein said open ends are located at a plurality of different distances from said support member surface, distance being measured along lines generally normal to said direction; and means for passing a gas through said conduits so that gas is released from said open ends of said conduits; whereby the bed of particles can be moved in said direction while gas is released in the bed at a plurality of depths therein.
Claim 7
Dependent Claim
37 words
An apparatus as recited in claim 4, wherein said plurality of conduits comprises a plurality of conduit arrays, said conduits in a particular array having open ends located at a particular distance from said support member surface.
Claim 8
Dependent Claim
32 words
An apparatus as recited in claim 5, wherein said conduit open ends for each array are positioned such that their distance to said support member surface progressively decreases in said predetermined direction.
Claim 9
Dependent Claim
14 words
An apparatus as recited in claim 6, wherein said support member is a grate.
