Thermal operating conditions of an RKZ-4-0-Il furnace in melting corundum

Conclusions Investigations were conducted of the thermal operating conditions of an RKZ-4-0-ll furnace, and complete energy balances of its operation were calculated. The primary energy losses occur through the gas exhaust system (9–17%), the furnace roof (14–25%), and the side walls and bottom of the furnace (13–36%).To increase the efficiency of the installation it is necessary to optimize the gas exhaust conditions and the cooling water consumption with simultaneous solution of the problem of utilization of the thermal losses and to convert the furnace to single tappings of larger volumes of molten material (or to increase the rate of tappings).Translated from Ogneupory, No. 1, pp. 48–53, January, 1984.
