연소가스관로의 방전영역 분리형 플라즈마 반응기에서 NOX, SOX 제거특성

초록

In this paper, discharge domain of wire-cylindrical plasma reactor was separated from a gas flow duct to avoid unstable discharge by aerosol particle deposited on discharge electrode and grounded electrode. The NOX, SOX removal was experimentally investigated by a reaction induced to ammonium nitrate., ammounium sulface using a low price of aqueous NaOH solution and a small quantity of ammonia.. Volume percentage of aqueous MaOH solution used was 20% and N2 flow rate was 2.5[ℓ/min] for bubbling aqueous NaOH solution. Ammonia gas(14.82%) balanced by argon was diluted by air and was introduced to a main simulated flue gas duct through NH3 injection system which was in downstreamof reactor. The NH3 molecular ratio[MR] was determined based on [NH3] to [NO+SO2]. MR is 1.5. The NOX removal rate slightly decreased with increasing initial concentration, but SOX removal rates decreased with increasing gas flow rate.
