ABSTRACT:
An infrared emittance combustion analyzer utilizing detectors in a flame burner which monitor the radiation at two preselected wavelengths. The respective radiation signals are filtered to eliminate DC signal variations, rectified and converted into a DC value which is representative of the measured radiation signals. The respective DC values are formed into a ratio which is compared against a predetermined setpoint signal, and the error signal resulting from this comparison is utilized to drive an electromechanical controller which adjusts either the air damper or the fuel damper to adjust the fuel/air mixture which is fed into the burner.
