PROBLEM TO BE SOLVED: To provide a method for efficiently blowing steam into gas-piping in a blast furnace. SOLUTION: In the method for blowing the steam for a power generator with furnace top pressure in the blast furnace, the steam is blown into the blast furnace gas from nozzles having multi-holes for gas-blowing, set at one or more positions in the blast furnace gas introducing gas-piping connected to the upstream side of the power generator with the furnace top pressure in the blast furnace.
