ABSTRACT:
The waste heat resulting from a coke oven operation is recovered in a two-stage proceeding. The waste gas is first cooled to not more than about 400.degree. C. in a recuperator or regenerator of the oven to principally utilize the heat radiation of the gas. Then, in a second stage, the gas is subjected to further cooling in a separate heat exchanger to principally exploit the heat convection of the gas. The process permits to recover waste gas on both basic principles of waste recovery, that is the recovery by radiation and the recovery by convection.
