Abstract
Apparatus for cooling hot particulate solids, especially shale solids, and reclaiming heat therefrom. The apparatus is constituted of an elongate housing divided into two compartments by a distributor plate sloped from 0.degree. to 15.degree. from horizontal, with jet openings therethrough declined downwardly from vertical at an angle between about 0.degree. to 45.degree.. The upper compartment contains a tube type heat exchanger and can be provided with a bed of solids. The lower compartment constitutes a plenum having a gas manifold with gas inlets for injection of gas into the manifold for release through the jets of the distributor plate. The gas is injected at velocities insufficient to fluidize a significant portion of the solids to maximize heat transfer between the solids and heat exchanger, and it contacts and expands the bed of solids, and assists in the downward movement of the solids along the distributor plate. Hot particulate solids are delivered to the bed of particulate solids in the upper compartment, contacted with the tubes of the heat exchanger through which a fluid coolant is passed, and cool solids are discharged via a cool solids outlet.
