| 摘要 |
The present invention relates to an energy saving type water gas reaction system. The water gas reaction system comprises: a fluidized reduction furnace for reducing powder type iron ore; a first heat exchanger for converting water into water vapor by using the heat of FOG (finex off gas) gas discharged from the top of the fluidized reduction furnace; a high-temperature reforming device producing and discharging a first gas containing hydrogen at a predetermined first temperature by using the FOG gas and the vapor generated from the first heat exchanger; and a second heat exchanger converting water into water vapor by using the heat of the first gas discharged from the high-temperature reforming device, wherein at least a part of the water vapor generated from the second heat exchanger can be reused in the high-temperature reforming device. |
