摘要
从对气体热辐射的微观机理的研究出发 ,利用谐振子模型对气体燃烧产物的热辐射特性进行了研究与计算 ,结果表明 :气体的热辐射波谱取决于气体分子的固有振动频率、等离子体频率、阻尼系数以及气层厚度 ,提高压力、气层厚度和降低温度可以有效地改善气体热辐射的选择性。
Based on the research to microscopic mechanism of gas heat radiation, the model of harmonic oscillator was established to study and calculate the heat radiative characteristics of flue gas. It is proved theoretically that the spectrum of heat radiation depends on the inherent vibrating frequency, plasm frequency, damping constant and the thickness of gas. Increasing the pressure or the thickness of gas and decreasing the temperature can improve the selectivity of gas radiation effectively.
