A method is provided for determining an operating state of a burner. The method includes receiving baseline characteristic data for a plurality of burner operating states. The baseline characteristic data for each burner operating state of the plurality of burner operating states comprises baseline data of a plurality of data types indicative of a corresponding burner operating state. The method also includes receiving monitoring data captured for a burner by a plurality of burner sensors. The method further includes using to machine learning to compare at least a portion of the monitoring data captured for the burner with the baseline characteristic data. The method still further includes determining an operating state of the burner based at least in part on results of comparing the at least a portion of the monitoring data with the baseline characteristic data. A corresponding apparatus and computer program product are also provided.
