This paper discusses applications of Fourier transform infrared (FT-IR) spectroscopy and laser spark spectroscopy (LSS) as in situ diagnostics for disperse phase combustion environments. The ultimate goal of the FT-IR work is the identification of gas phase species, and the determination of their temperature and concentration during the combustion of pulverized coal particles. The authors are developing LSS as a complementary technique for the in situ elemental analysis of coal, char, and ash particles in combustion environments.
