Provided is an apparatus for reducing carbon dioxide by using hot molten slag and a flue gas containing carbon dioxide. The apparatus includes a slag atomizer spraying the molten slag to form slag powder, a carbonization reactor for a carbonization reaction between the slag powder and the carbon dioxide, and a flue gas supplying device for supplying the flue gas containing the carbon dioxide to the carbonization reactor. According to the present embodiment, hot molten slag, which is a by-product generated while manufacturing ingot iron, and a flue gas containing a high concentration of carbon dioxide are reacted with each other to precipitate carbonate, thereby reducing the generation of carbon dioxide from the flue gas generated while manufacturing the ingot iron. Also, heat generated during the carbonization reaction between the slag and the flue gas is collected to be used, thereby increasing the energy efficiency of the ingot iron manufacturing process. |
