FLUIDIZED BED GASIFICATION FURNACE

摘要

A fluidized bed gasification furnace (1) includes a control device (20) that identifies a defective fluidization spot of a fluidized bed (9) based on distribution of temperatures detected by a plurality of temperature sensors (21, 22, 23, 24, and 25), temporarily increases an amount of supplied combustion gas to air boxes (10) located below the identified defective fluidization spot, and increases a speed of discharge of noncombustibles and a fluidization medium discharged by an extruder (13).
