    Abstract: Systems and methods for multi-level optimization of emission levels and efficiency for a boiler system that includes creating both boiler-level models (516) and burner-level models (524) and receiving a plurality of boiler-level system variables. The received system variables are used along with boiler system constraints to optimize boiler-level setpoints. Once the boiler-level setpoints have been optimized they are sent to the burner level (504) of a hierarchical control system (302), where they are used to optimize burner-level setpoints. Once the burner-level setpoints have been optimized they are sent to the burner control loops (530) of the plant control system (506) to be implemented.
