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.

摘要：本文研究了脉冲电晕放电在燃烧排放物中破坏一氧化氮（NO）和氧化亚氮（N2O）的机理和中间体。原位激光诱导荧光（LIF）将用于研究等离子体诱导破坏煤田流化床燃烧（FBC）系统排放物中氮氧化物的氢原子、羟基径向和一氧化碳的行为。虽然电晕放电被认为是一种很有前途的技术，用于控制来自移动和固定来源的氮和硫氧化物，但以前的研究只关注稳定的最终产物。这是对这一过程机理的初步探索，为优化制度提供了合理依据。
