- Abstract
- We have used Fourier transform infrared (FT-IR) spectrometry to make in situ measurements of the gases present in hot, particle-laden environments. UsingFT-IR, it is possible to measure simultaneously the composition and temperature of gases produced during combustion. Like other optical techniques, these measurements do not perturb the chemical or flow characteristics of the combustion processes. Furthermore, the large spectral region sampled using FT-IR permits quantitative determination of low molecular weight gases (CO, CO2, H2O, etc.) and hydrocarbons as well as qualitative determination of heavier hydrocarbons. We report here, preliminary results for pulverized coal combustion. These results are compared to those obtained earlier for gaseous hydrocarbon combustion in which large amounts of soot were produced.
