Abstract: A bulk hot coke cooler with a vessel for holding the coolant material and a drum rotatably supported within the vessel so that when the drum rotates, it moves through the coolant, the drum having a plurality of hollow cooling pockets going from one side of the drum to the other which directly contact the hot coke in the drum through which pockets coolant can flow as the drum rotates to enhance the cooling effect of the coolant on the hot coke inside the drum, the pockets having end walls which close off the pockets forming an inlet and an outlet for the coolant, the drum wall not overlapping the pocket end wall. Transfer bars formed integrally of the pockets can be used to facilitate coke movement.

Abstract: A bulk hot coke cooler with a vessel for holding the coolant material and a drum rotatably supported within the vessel so that when the drum rotates, it moves through the coolant, the drum having a plurality of hollow cooling pockets going from one side of the drum to the other which directly contact the hot coke in the drum through which pockets coolant can flow as the drum rotates to enhance the cooling effect of the coolant on the hot coke inside the drum, wear sleeves provided on the edges of selected pockets to protect the lead surfaces of the pockets which come in contact with the hot coke, the wear sleeves being shaped to match the shape of the pocket surface where they are attached, and transfer bars connected to the wear sleeves which move and push the coke through the drum. The various parts of the cooler can be fabricated from hardfaced plate.
