Abstract
A system and a method for decreasing a rate of slag formation at predetermined locations in a boiler system are provided. The boiler system has a plurality of burners, a plurality of slag detection sensors, a plurality of temperature sensors and a plurality of CO sensors disposed therein. The system determines locations within the boiler system that have relatively high slag thickness levels utilizing the plurality of slag detection sensors 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, and the plurality of CO sensors.
