A. ISB uses weight measured by SmartGauge and cleanliness factors calculated by thermodynamic model to determine the fouling condition in the pendants and backpass areas and direct the sootblower when and where to clean. The feedback from heat flux sensor is used to determine the operation of water cannon which cleans the water wall.
