The Study of Dynamic Diagnostics for Measuring H{sub}2O and CO{sub}2 Concentrations in Post-Combustion Gases by Absorption Spectroscopy

摘要

We study dynamic diagnostics for measuring H{sub}2O, OH, CO and CO{sub}2 concentration in Post-Combustion gases by using absorption spectroscopy. This paper presents an algorithm using the spectra distribution that relates the concentrations and absorption by using Beer Lambert and Hitran2000. The results of simulation on the laminar flame combustion at 1500K and 1500K give the information on the behavior and interference-action in the detected species under known conditions providing the foundation to develop a practical instrument for measuring the concentration of gas species in the combustion environment.
