Application of an Imaging Fourier-Transform Spectrometer for the Means of Combustion Diagnostics

Abstract

A passive remote sensing technique for accurately monitoring the combustion efficiency of petrochemical ares is greatly desired. A Phase II DOE-funded SBIR lead by Spectral Sciences, Inc. is underway to develop such a method. This paper presents an overview of the current progress of the Air Force Institute of Technology's contribution to this effort. A Telops Hyper-Cam Mid-wave infrared (MWIR 1800-6667 cm(-1) or 1:5-5:5 mum) imaging Fourier-transform spectrometer is used to examine a laminar calibration ame produced by a Hencken burner. Ethylene fuel (C2H4) was burned at four different equivalency ratios Phi = 0:80; 0:91; 1:0 and 1:25. Presented is qualitative spectrally-resolved visualization of a Hencken burner ame and the spatial distribution of combustion by-products.
