Title:
焼結設備用廃熱回収発電プラント
Document Type and Number:
Japanese Patent JP5813344
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a waste heat recovery power generation plant for sintering facility which is capable of effectively recovering waste heat of a sintering machine in addition to a sintered ore cooler while suppressing the droplet sulfation of sulfuric anhydride containing in an exhaust gas of a sintering machine.SOLUTION: Hot water obtained by heating a condensed water of a steam turbine 51 and returned hot water of a low pressure stage flasher 42 using an economizer 37 of a sintered ore cooler waste heat boiler (SC boiler) 30 is distributed to a steam drum 36 of the SC boiler, a steam drum 16 of a high pressure stage flasher 41 and a sintering machine waste heat boiler (SM boiler) 10 and high pressure steam obtained by an evaporator 35 and a superheater 33 of the SC boiler and high pressure steam obtained by an evaporator 15 and a superheater 13 of the SM boiler are supplied to a high pressure stage of the steam turbine 51, the steam of the high pressure stage flasher 41 is supplied to a medium pressure stage, steam of a low pressure flasher 42 is supplied to the low pressure stage. The sintering machine waste gas is always kept at a temperature equal to or above the acid dew point by the waste recovery power generation plant supplying the steam of the low pressure flasher 42 to the low pressure stage.
