APPARATUS FOR GENERATING ENERGY USING A SENSIBLE HEAT DURINGMANUFACTURING OF MOLTEN IRON AND METHOD FOR GENERATING ENERGY USING THE SAME

摘要

An apparatus for generating energy using sensible heat of an offgas durin g manufacture of molten iron and a method for generating energy using the sa me are provided. The method for generating energy includes i) providing an o ffgas discharged from an apparatus for manufacturing molten iron including a reduction reactor that provides reduced iron that is reduced from iron ore and a melter- gasifier that melts the reduced iron to manufacture molten iro n; ii) converting cooling water into high pressure steam by contacting the c ooling water with the offgas; and iii) generating energy from at least one s team turbine by supplying the high pressure steam to the steam turbine and r otating the steam turbine.
