Patent ID: 8070482

Claim:
A system of detection, analysis, and control of a gas or fuel oil flame of a burner of a boiler, industrial furnace or other equipment with a combustion process, including: a. an optical sensor that targets the reaction zone of the flame, including a first photodetector for detecting an emission of the gas or fuel oil flame at 432 nm and generating a first signal as the absolute intensity of free radical CH, and a second photodetector for detecting the emission of the flame at 516 nm and generating a second signal as the absolute intensity of free radical C2; b. a processing and control module receiving and processing the first signal and second signal, and generating a processed signal corresponding to a ratio of the second signal to the first signal; and c. an actuator receiving the processed signal as an input and manipulating and controlling an airflow damper in response to the processed signal wherein the processing and control module constantly monitors the CH and C2 levels and constantly sends a signal to the actuator to adopt an ideal burner damper position by constantly maximizing the ratio of C2/CH, thereby increasing boiler efficiency and diminishing pollutant emission levels.
