FLUIDIZED-BED GASIFICATION METHOD AND FACILITY THEREFOR

摘要

A fluidized bed gasification facility comprises a fluidized-bed combustion furnace (1), a separator (8) for separating a bed material (11) from exhaust gas, a fluidized-bed gasification furnace (40) into which the bed material (11) is introduced through a down comer (46) and a material is also introduced, a channel for circulating char and the bed material (11) through the fluidized-bed combustion furnace (1), a dispersion section (43) extending in the width direction of a wall portion (41), which is on the side for introducing the bed material and constitutes one side surface of the fluidized-bed gasification furnace (40), and receiving the bed material (11) from the down comer (46), a fluidized gas introduction means (47) for fluidizing the bed material (11) in the dispersion section (43) by blowing fluidized gas there into, and a section (48) for supplying the bed material (11) from the dispersion section (43) into the fluidized-bed gasification furnace (40) uniformly across the overall width on the side for introducing the bed material.
