ABSTRACT:
A flame analyzer for analyzing one or more qualities of a flame from a burner, comprises a fiber optic array including a plurality of optic fibers each having a light-receiving end lying in a line and facing the flame. The line extends parallel to the flame and burner axis or may extend perpendicular to that axis. The light received by the fiber optic array is provided as a sheet of light to a monochromator which spreads the light into its component wave lengths. A pair of spaced apart arrays of light detectors is then utilized to measure the light at two discrete wave lengths. The detection produces signals that can be analyzed to generate temperature and particles distribution values for the flame across its length or width.
