ABSTRACT:
A process for utilizing waste heat and producing water gas during cooling of red-hot coke, in two stages, is indicated. In a first, dry cooling stage, a mixture of water gas and steam passes the coke charge, is recooled in a heat sink and recirculated into the first cooling stage, whereby it is possible to take off a part quantity of the gas mixture. In a second, wet cooling stage, water is fed into a quench zone and the steam formed is passed through the coke charge partially into the first cooling stage and partially released into the surroundings or fed back into the second cooling stage or partly released into the surroundings and partly fed back into the second cooling stage. Both the mixture of water gas and steam in the first cooling stage and the quench water or the steam formed from it in the second cooling stage are passed through the coke charge from the inside outwards.
