<p>PROBLEM TO BE SOLVED: To stably supply electric power even at the time of periodically interrupting the operation for repairing a furnace body refractory and to efficiently execute the operation after interrupting the furnace operation, in plural sets of smelting reduction furnaces having one set of a waste heat boiler and an electric power generating equipment. SOLUTION: In this operating method of the smelting reduction equipment provided with one set of the waste heat boiler 12 for recovering by vaporization the sensible heat and latent heat of combustible gas generated from plural furnace bodies 1a, 1b and the electric powder generating equipment 18, and the waste heat boiler 12 and the electric powder generating equipment 18 are connected to plural furnace bodies, 1a, 1b through an exhaust gas confluent duct 31 and exhaust gas ducts 6a, 6b freely adjusting the opening degree, in the case of preparing the operation of the furnace body during stopping the operation, in plural sets of furnace bodies 1a, 1b, the combustible gas generated from the furnace body during operating in the plural sets of furnace bodies, 1a, 1b, is introduced to the furnace body during preparing the operation so as to execute the operating preparation by utilizing the combustible gas.</p> |
