A rotary coke cooling drum is formed of plural opposed folded plates welded together and having spaced apart openings for receiving an array of tubular cooling pockets which are separately formed and are insertable in the openings to provide heat transfer surfaces and auger flights for traversing material through the drum. The cooling pockets are formed by opposed trapezoidal shaped plate members which are welded to each other along mating edges leaving one end of the cooling pocket substantially open and the opposite end is closed over a major portion by an end cap and a short section of drain conduit adapted to project through the wall of the drum shell. The cooling pockets may each have a locating and mounting flange or doubler plate secured at the open end of the pockets and adapted to be welded to the wall of the drum shell. The pockets are easily inserted in and removed from the drum shell for repair or replacement as needed.
A coke cooling apparatus comprising an elongated rotatable drum having a circumferential wall forming a hollow drum shell and a plurality of axially and circumferentially spaced cooling pockets supported inside said drum shell for cooling coke in said drum shell and for augering said coke through said drum shell, each of said cooling pockets comprising an elongated tubular member having opposed, planar sidewalls, an end cap secured to said sidewalls at one end, the other end of said cooling pocket being open and a drain conduit formed at said one end, said cooling pocket being insertable in a first opening formed in said drum shell and including a flange for securing said cooling pocket to said drum shell, said drum shell including a smaller second opening formed opposite said first opening for receiving said drain conduit.
A cooling pocket for a rotary coke cooling drum for collecting and holding a quantity of cooling water as said cooling drum rotates through a cooling water bath, said cooling pocket comprising:
