ABSTRACT:
A method for the indirect cooling of hot gases, particularly, coke oven gases using a gas cooler having a cooling chamber with three different heat exchangers arranged therein, comprises directing the gases to be cooled through first one of the heat exchangers while circulating a coolant through the first heat exchanger which comprises a heater agent taken from the desorber stage of an absorber-desorber-type refrigerating machine. The gases are then directed through the second heat exchanger while circulating ordinary cooling water therethrough and, thereafter, the gases are directed through a third heat exchanger while the heating agent from an evaporator stage of the refrigerating machine is circulated through the third heat exchanger. The apparatus includes a gas cooler housing having the various first, second and third heat exchangers therein, and with a refrigerating machine connected in a circuit for supplying a higher temperature transfer medium to the first heat exchanger and a coolant medium below the temperature of the cooling water to the third heat exchanger.
