Two-dimensional distribution of ground-state NO density by LIF technique in DC needle-to-plate positive streamer coronas during NO removal processing

Two-dimensional distribution of the ground-state NO molecules density was i nvestigated using laser-induced fluorescence (LIF) technique in a de positi ve streamer Corona reactor (needle-to-plate electrode geometry) during NO r emoval from a flue gas simulator (NO/air). NO density in the Corona dischar ge reactor was monitored under the steady-state dc Corona discharge conditi on. It was found that NO molecules density decreased due to the Corona disc harge processing not only in the discharging region but also in the upstrea m vicinity of the discharge.
