Flue gas treatment by high-pressure pulsed glow discharge in gaseous and liquid hybrid medium

点击翻译按钮获取中文摘要

High-pressure, pulsed glow discharge is applied to treat the flue gas. The peak power of the discharge reaches 171 MW with the pulse duration of 50 ns. It is found that up to 40 % of the VOC (formaldehyde) is treated by firing 10 shots of the discharge. The spectrum of light emission form the discharge is measured to estimate the treatment process. The strong lines of N and O are confirmed, while the line of OH radical is weak. It indicates that electron impact with the formaldehyde is considerable path for the VOC treatment.
