SYSTEM AND METHOD FOR DECREASING A RATE OF SLAG FORMATION AT PREDETERMINED LOCATIONS IN A BOILER SYSTEM

摘要

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