  • Patent number: 4264415
    Abstract: An apparatus for the dry cooling of coke is disclosed including a vertical cooling chamber having an open bottom, a gas distribution manifold disposed in the bottom of the cooling chamber and a pair of discharge openings for the continuous withdrawal of the cooled coke from the bottom of the chamber. The cooling gas manifold includes upwardly sloping walls which intersect at an apex located generally centrally of the bottom of the cooling chamber. Gas discharge openings extend through these walls and are so disposed as to make cooling gas available across the entire cross-section of the cooling chamber. Individual, closed gas chambers communicate with groups of the gas discharge openings and the flow of gas to each chamber is individually regulated.
