Laser Raman Spectroscopy of Flames; Temperature and Concentrations in CH4/N2O Flames

摘要

A laser Raman spectroscopy apparatus has been used to obtain temperature and major species (N2, H2, CO, cO2, and H2O) concentration measurements in the burnt gas region of CH4/N2O flames. Temperatures measured were in the range of 2100 to 2500 K with computed errors of less than 50 K. The concentration measurements are in good agreement with thermochemical equilibrium calculations.
