Abstract
Burner operating air equivalence ratio is monitored and controlled by a method comprising measuring OH radical spectral emission intensity at a base of a flame while combustion is in progress at a burner, employing a linear relationship between the intensity and an actual burner operating air equivalence ratio to determine the ratio while combustion is in progress, comparing the determined ratio with a desired burner operating air equivalence ratio to determine the difference therebetween, and controlling the amount of air supplied to the burner on the basis of the difference.
