EXHAUST HEAT RECOVERY POWER GENERATION PLANT FOR SINTERING FACILITY

摘要

To provide an exhaust heat recovery power generation plant for a sintering facility in which it becomes possible to effectively recover exhaust heat from a sintering device in addition to a sintered ore cooler while controlling the sulfation of anhydrous sulfuric acid droplets included in the exhaust gas of the sintering device. [Solution] An SM boiler (10) heats all or part of the hot water generated by an SC boiler (30) by introducing the high temperature portion of exhaust gas from a sintering device (1). At this point the temperature of the hot water supplied to the SM boiler (10) is controlled so as to maintain the temperature of the exhaust gas in the exhaust gas outlet of the SM boiler (10) above the acid dew point.
