Paper Abstract

12 The present work reports measurements on a General Electric Dry Low NOx premixed combustor (mod. DLN for gas turbine LM 1600, 2500 and 6000) by using broadband Coherent Anti-Stokes Raman Spectroscopy in the planar BOXCARS configuration. Experimental spectra have been compared with theoretical nitrogen spectra at atmospheric pressure through a neural network analysis. In order to obtain instantaneous temperature measurements the simulated spectra have been calculated in a wide range of temperatures (300 - 2500 degree(s)K), thus permitting a fast comparison with the experimental spectra obtained from the flame. The data obtained in this work are now used to test numerical simulations of kinetic and chemical models employed in the code FLUENT.
