Abstract

Operation of a combustion control system of furnace is controlled by image analysis, outside of the furnace or within the furnace, of a flame produced by combustion within the furnace, to correlate the image with carbon monoxide content of the flame, and adjustment of the oxygen and/or fuel flow into the furnace in response to the correlation.
