Abstract:
A system and a method for decreasing a rate of slag formation at predetermined locations in a boiler system (12) are provided. The boiler system (12) has a plurality of burners (47, 48, 50, 52), a plurality of slag detection sensors (116, 118, 120 121), a plurality of temperature sensors (110, 112, 114, 115) and a plurality of CO sensors (94, 96, 98, 99) disposed therein. The system determines locations within the boiler system (12) that have relatively high slag thickness levels utilizing the plurality of slag detection sensors (116, 118, 120 121) and then adjusts A/F ratios or mass flows of burners affecting those locations, or adds slag reducing additives to the burners affecting those locations, to decrease a rate of slag formation at the locations, utilizing signals from the plurality of slag detection sensor, the plurality of temperature sensors (110, 112, 114, 115), and the plurality of CO sensors (94, 96, 98, 99).

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.
Abstract:
A sample probe includes a sample probe tip filter (50, 70). The sample probe also includes a shield (52, 72) disposed in relation to the sample probe tip filter (50, 70), the shield (52, 72) being operable to deflect particles in a gas sampling stream (14) away from the sample probe tip filter (50, 70). The shield (52, 72) has at least one opening (60, 62, 76) that allows the gas within the gas sampling stream (14) and certain ones of the particles in the gas sampling stream (14) both traveling in a substantially flow reversal direction (66) to a primary direction (18) of the gas sampling stream (14) to enter the shield (52, 72) and contact the sample probe tip filter (50, 70).
