Abstract (en)
A gasification and slagging combustion furnace comprises a fluidized-bed gasification furnace (1) as a preceding stage and a slagging combustion furnace (2) as a succeeding stage. The recovered fluidized medium (d) is transferred to the fluidized-bed gasification furnace where the fluidized medium is reused. A metal component (a,b,c) is separated and recovered from the furnace-bottom residue. A nonmetal component is utilized after matter comprising the nonmetal component is rubbed with one another to remove contaminants from the surface of the matter, or after removing by a screen a powder component contained inherently in the nonmetal component and a powder component produced upon crushing of the nonmetal component. Alternatively, a nonmetal component is crushed to produce powder (e), the produced powder is transferred to the fluidized-bed gasification furnace, and then to the slagging combustion furnace where slagging is performed.
