Abstract
An apparatus is disclosed for distributing solid particles of the type having a stationary sub-assembly for feeding particles, and positioned at its lower portion, a rotary sub-assembly for distributing the particles, wherein the rotary distribution sub-assembly includes an axial gas feed conduit (10) configured and dimensioned to exit a fluidization gas under a fluidization grate (20) positioned in the lower portion of a centrally located vat (16). The upper peripheral portions of the vat have connected thereto a plurality of radially extending particle distribution conduits (34). All but one of the distribution conduits (34) are generally straight and are of different lengths. These conduits (34) are connected to the vat at approximately the same vertical level and are slanted approximately equally downwardly about 30.degree.. One of the distribution conduits (34.sup.a) is configured to contain a bend so as to direct solid particles toward the rotational axis of the rotary distribution sub-assembly.
