METHOD FOR TRANSPORTING IMPURITIES IN PRESSURIZED FLUIDIZED FURNACE SYSTEM

摘要

To convey efficiently impurities in a dust collector into the outside. Cleaning gas is supplied to an upper valve (52), and thereafter, the upper valve (52) is driven so as to communicate an upper discharge device (51) and a tank (53), the upper discharge device (51) is driven so as to convey the impurities from the dust collector (50) to the tank (53), and thereafter, the upper discharge device (51) is stopped, and the upper valve (52) is driven so as not to communicate the upper discharge device (51) and the tank (53), and thereafter, the supply of the cleaning gas to the upper valve (52) is stopped.
