ADAPTIVE DEVICE OF BURNER FLAME MONITORING Russian patent published in 2013 - IPC F23N5/08 

FIELD: power engineering.

SUBSTANCE: device comprising a photo diode, an amplifier-converter and an analyser is added with a circuit of normalisation of the analyser input signal. The normalisation circuit comprises an integrator. The amplifier-converter is made with the possibility of separation of a variable component in the photo diode signal, its strip amplification and single-sided limitation and fixed shift of the potential level of the input signal of the analyser, the normalisation circuit is made as capable of elimination of deviations of the time-average value of the input analyser signal from the normal signal.

EFFECT: invention increased reliability of selective monitoring of a single burner flare with expansion of the range of burnt fuel types.
