Abstract

Two-dimensional distribution of the ground-state NO molecules density was investigated using a laser-induced fluorescence (LIF) technique in a DC positive streamer corona reactor (needle-to-plate electrode geometry) during NO removal from a flue gas simulator (NO/air). NO density in the corona discharge reactor was monitored under the steady-state DC corona discharge condition. It was found that NO molecules density decreased due to the corona discharge processing not only in the discharging region but also in the upstream vicinity of the discharge
