Abstract : A device for monitoring combustion efficiency of a burner with a burner flame has an acoustic sensor probe positioned within the burner, flame signature generating circuitry responsive to the acoustic probe, means for correlating flame signatures with known optimum efficiency characteristics to yield an indication of relative combustion efficiency, and output means for display of the relative combustion efficiency. This invention relates to an Acoustic Combustion Efficiency Analyzer. Combustion equipment is sensitive to changes in atmospheric conditions. Insufficient air results in incomplete combustion of fuel; excess air quenches flame temperature and reduces the efficiency of heat transfer. Also, combustion equipment, particularly of the oil fueled variety, is readily thrown out of adjustment by such phenomena as progressive fouling. Constant and precise burner flame adjustments are required in order to maximize burner efficiency in the presence of atmospheric changes and progressive fouling. Pat CL-370-577. (JS)
