摘要:
A method for operating a filtration apparatus for flue gas, which removes dust from flue gas discharged from a burner using mainly solid fuel, wherein incombustible powder is introduced into the filtration apparatus upon detecting or foreseeing coming of unburnt combustible dust from the burner, or upon detecting or foreseeing a temperature rise of the flue gas, and the incombustible powder is suspended in the dust-containing flue gas to suppress combustion of the combustible dust, or to suppress the temperature rise of the flue gas, in the filtration apparatus.
