PROBLEM TO BE SOLVED: To provide a method for transporting impurities in a pressurized fluidized furnace system, to efficiently transport impurities in a dust collector to the outside.SOLUTION: After a cleansing gas is supplied to an upper valve, the upper valve is activated and an upper extraction device and a tank are connected. After an upper extraction device is activated and impurities in a dust collector are transported to the tank, the upper extraction device is stopped. After the upper valve is activated to disconnect the upper extraction device from the tank, the supply of cleansing gas to the upper valve is stopped. |
