Abstract
The present disclosure provides an oxygen-enriched combustion flame detection method, device and electronic equipment. The method comprises: monitoring a target burner to obtain monitoring data of the target burner in a target time period; wherein the monitoring data comprises a first nitrogen oxide concentration and a first to-be-measured audio signal; obtaining a standard nitrogen oxide concentration corresponding to the first nitrogen oxide concentration for a first set time period, and obtaining a standard audio signal corresponding to the first to-be-measured audio signal for a second set time period; and determining a flame combustion state of the target burner in the target time period according to the first nitrogen oxide concentration and the standard nitrogen oxide concentration, and the first to-be-measured audio signal and the standard audio signal. Thus, the oxygen-enriched combustion flame combustion state of the target burner can be automatically identified based on the nitrogen oxide concentration and the to-be-measured audio signal.
