烟道气体SO2光谱辐射强度和吸收系数的研究
Calculations of the spectrum intensities and absorption coefficients of SO2 flue gas
摘要
Abstract
The total internal partition functions of SO2 flue gas are calculated with the product approximation. Using the calculated transition moment squared, Herma-Waills factor coefficients and the calculated partition functions, we computed the spectrum intensities and of 001 — 000 transitions of SO2 flue gas at 500 K and 3000 K. The results show that the calculated values of the total internal partition sums and spectrum intensities are all consistent with the data obtained from HITRAN04 database (the deviation value is less than 3%). Such excellent agreements lend us much credibility in the calculations of spectrum absorption coefficients at different temperatures. From the spectral figs at different temperatures, we find that the intensities significantly reduce and the spectral band heart is invariable with the increase in temperature. The absorption coefficients will reduce with the increase in temperature, the absorption peak position will broaden below 3000 K and is basic invariant above 4000 K. This will provide experimental and theoretical reference for monitoring flue gas environmental pollution.关键词
