<p>PROBLEM TO BE SOLVED: To provide an equipment which can increase waste heat power generation by utilizing the waste heat of a cooling panel practically difficult to recover and heating water at the outlet side of a steam condensor in a steam turbine, i.e., at the inlet side of an waste heat boiler, in the waste heat recovering equipment of a smelting reduction durance. SOLUTION: The exhaust heat recovering equipment of the smelting reduction furnace which directly produces molten iron or molten pig 6 by adding iron raw material, carbonaceous material and slag-making agent into the furnace body 1 lined on the cooling panel and blowing pure oxygen and/or oxygen- enriched gas and also, vaporizes supplied water with the waste heat boiler 10 by utilizing the heat of combustion gas discharged from the furnace body 1 to recover the steam in a vapor turbine 21. In such a case, a piping at the outlet side of the steam condenser 22 in the steam turbine is connected with the inlet side of the cooling panel and a piping 14 at the outlet side of the cooling panel is connected with the inlet side of a degassing device in the steam turbine and a system for supplying the warm draining water and/or the steam generated in the cooling panel into the deaerating device 24.</p> |
