Laser-Induced Fluorescence Diagnostic Studies of Reactive Species in a Pulsed Corona Reactor

本文研究了脉冲电晕放电去除燃烧废气中一氧化氮(NO)和一氧化二氮(N2O)的机理和中间产物。利用原位激光诱导荧光(LIF)技术研究了煤田流态化燃烧(FBC)系统中氢原子、羟基自由基和一氧化碳在等离子体诱导的氮氧化物降解过程中的行为。虽然电晕放电被认为是一种很有前途的技术，可以控制移动和固定来源的氮氧化物和硫氧化物，但以前的研究只关注稳定的最终产物。这是首次尝试对该过程的机理进行研究，为系统的优化提供合理的依据。

ABSTRACT AGARWALThis is a study of the mechanism and intermediates in the destruction of nitric oxide (NO) and nitrous oxide (N2O) in combustion emissions using a pulsed corona discharge. In situ laser-induced fluorescence (LIF) will be used to study the behavior of hydrogen atoms, hydroxyl radials, and carbon monoxide in the plasma-induced destruction of nitrogen oxides in the emissions from a coal-field fluidized bed combustion (FBC) system. Although corona discharge is regarded as a promising technology for control of nitrogen and sulfur oxides from both mobile and stationary sources, previous studies have looked only at the stable end products. This is the first attempt to investigate the mechanism of the process and provide a rational basis for optimizing the system.
