Abstract

DC60 (21/02/14) Invented currently involves a process for treating iron by treating iron. By heating in the furnace for heat treatment (2) and acid immersion in the immersion solution. Acid for iron (3) When the process air released from the iron-soaked solution (3) is heated to the catalyst's operating temperature and fed to the catalyst (5) to reduce the nitrogen concentration. Oxides when the air released from the catalytic process (5) is fed as air for combustion to at least one thermal burner (20). The machines of the furnaces for heat treatment (2) invention currently involve a series of tools. For iron treatment (1) with a blast furnace for heat treatment (2) for treatment with Iron heat Acid immersion solution for iron (3) for soaking iron in acid and catalyst (5) to reduce the nitrogen oxide concentration of air released from the source process. From an acid-soaked solution for iron (3) when the apparatus for heating (6,60) for heating the air released from the process before the catalyst (5) is provided for heating. The air released from the process goes to the temperature of the catalyst's performance. When the feeding device (32) for the feeding of the air released from the catalytic process (5) goes to at least one heat treatment furnace (20) of the furnace for heat treatment (2). Has been made to present a process for the treatment of iron by treating By heating in a furnace for heat treatment (2) and acid immersion in solution. Soak acid for iron (3) When the process air released from the iron infusion solution (3) is heated to the catalyst's operating temperature and fed to the catalyst (5) to reduce the concentration of Nitrogen oxides when the air released by the process through a catalyst (5) is fed as air for combustion to at least one burner (20). Of furnaces for heat treatment (2) invention currently involves a set of tools for Iron treatment cannon (1) with blast furnace for heat treatment (2) for heat treatment of iron, acid-soaked solution for iron (3) for soaking iron in acid and catalyst. (5) To reduce the nitrogen oxide concentrations of the air released by the process coming from Acid-immersed solution for liquids (3) when the equipment for heating (6,60) for the It heats the air released from the process before a catalyst (5) is provided for heating. The air released from the process goes to the temperature of the catalyst's performance. When the device is for Feeding (32) for the feeding of the released air from the catalytic process (5) to At least one sintering furnace (20) of the sintering furnace for heat treatment (2) is provided with
