である。As detailed above, according to the present invention, carbon dioxide in the components is removed from all or part of blast furnace gas to make it high in calories, and stable combustion is achieved using only this high calorie blast furnace gas as fuel. Since the gas turbine connected to the generator is driven to rotate, there is no need to use another high-calorie fuel such as diesel oil or propane gas as a combustion improver, resulting in low friction and low operating costs. This system has the advantage of being able to obtain the required electricity, and as a by-product, not only high-pressure steam as in the past, but also highly purified carbon dioxide gas can be recovered.
