A base housing section, a plurality of intermediate housing sections, and a head housing section are stacked one above the other in a gas-tight but readily removable manner, to form a hollow housing. The base housing section and head housing section are equipped with gas connections so that a gas from a coke plant may be circulated through the hollow housing. Each intermediate housing section has extending transversely across the interior thereof at least one group of a plurality of heat exchange tubes. Cooling fluid connection means are connected to the uppermost and lowermost groups of tubes for the passage therethrough of a cooling fluid. Adjacent ends of adjacent groups of the tubes are connected such that the heat exchange fluid passes through all of the tubes of the intermediate housing sections in a substantially sinusoidal manner. |
