The energy formation device which utilizes the sensible heat of the waste gas at the time of iron production and the energy formation method of utilizing this

摘要

An apparatus for generating energy using sensible heat of an offgas during manufacture of molten iron and a method for generating energy using the same are provided. The method for generating energy includes i) providing an offgas 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 iron; ii) converting cooling water into high pressure steam by contacting the cooling water with the offgas; and iii) generating energy from at least one steam turbine by supplying the high pressure steam to the steam turbine and rotating the steam turbine.
