Abstract

A device and method for dry cooling incandescent coke comprises a closed cooling chamber having a coke inlet, for example, at its top end and a coke delivery or discharge at its bottom end which is subdivided by a plurality of vertical walls so as to leave coke flow spaces between the walls. The walls are constructed to define a continuous meandering path for coolant which is circulated through the walls during the flow of coke therethrough. The walls comprise superposed ducts arranged vertically one over the other and which for example are welded together and which have respective ends connected to a superjacent or subjacent duct so as to form a continuous meandering coolant flow passage. The coolant is circulated through inlet and outlet connections arranged exteriorly of the chamber and the coke flow and coolant flow are controlled through the chamber as desired to affect the cooling rate selected.
