PURPOSE: An electric power generation method and structure using a dual heat exchanger of a blast furnace are provided to generate electricity through a steam turbine of a generating part, which is actuated with high-temperature high-pressure steam created through a furnace part. CONSTITUTION: In an electric power generation structure using a dual heat exchanger of a blast furnace, a dual heat exchanger(14) located in a furnace part(10) generates high-temperature high-pressure steam with heat of 1500°C created from a hot blast stove(12) and pulverized coal(13) on the basis of the heat flow in the dual heat exchanger. According to the heat flow in the dual heat exchanger, the heat created from the hot blast stove and the pulverized coal is returned to a blast furnace(11) after used.
