<p><P>PROBLEM TO BE SOLVED: To provide a fluidized bed gasification method by which a fluidizing medium can suitably be spread to all the corners of a fluidized bed gasification furnace, even when the fluidized bed gasification furnace is enlarged, and to provide a facility therefor. <P>SOLUTION: Provided is the facility for the method, comprising a fluidized bed combustion furnace 1, a separator 8 for separating a fluid medium 11 from an exhaust gas, a fluidized bed layer gasification furnace 40 into which the fluid medium 11 is introduced through a falling pipe 46 and into which a raw material is also introduced, a circulation flow channel for circulating char and the fluid medium 11 to the fluidized bed combustion furnace 1, a dispersing portion 43 extended in the width direction of a fluid medium-introducing sidewall portion 41 constituting one side surface of the fluidized bed layer gasification furnace 40 and receiving the fluid medium 11 from the falling pipe 46, a fluidizing gas-introducing means 47 through which the fluidizing gas is blown into the dispersing portion 43 to fluidize the fluid medium 11 in the dispersing portion 43, and a supply portion 48 for approximately uniformly supplying the fluid medium 11 in the dispersing portion 43 into the fluidized bed layer gasification furnace 40 over the whole width of the fluid medium-introducing side. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
