Taylor, D J

Coherent anti-Stokes Raman spectroscopy (CARS) is a promising optical diagnostic for species concentrations and temperature in the gas streams of coal gasifiers. The CARS technique will supply real-time process data more rapidly than any currently available technique. Moreover, CARS is nonintrusive and requires no sample handling. We have successfully observed CARS signals in the most hostile gasifier stream of the METC coal gasifier from majority and some minority molecular components. Our current program aims to improve the quantitative accuracy of CARS measurements of concentrations and temperatures in coal gasifier streams by the development of a comprehensive data base and of appropriate experimental normalization techniques. 5 figures.
