DEVICE FOR PREVENTING DEPOSITION OF DUST TO INSIDE OF FLUE

摘要

PURPOSE:To prevent deposition of dust to the inside surface of a flue wall by installing a deelectrifying device to an upstream side of the flue and neutralizing electrically dusts flowing through the flue and charged to positive or negative polarity. CONSTITUTION:Gas discharged from a boiler, etc., and contg. electrically charged dusts is discharged to atmospheric air through a flue 1 GGH 2, and a stack 3. A deelectrifier 4 is disposed to the flue 1 at the upstream side of the flow of the gas in GGH 2, and electrically charged dusts in the flue are neutralized when a passing through the deelectrifier 4 by the deposition of ions having reverse polarity to the polarity of the electrified dust among the ions generated by the deelectrifier, to the dusts. Thus, the deelectrified dusts loose electrically depositing effect, so they are discharged to atmospheric air without causing sticking to the inside surface of the flue wall.
