Power

This problem is compounded over time as sliding wear can increase the gap between the soot blower lance and the port hole, allowing excessive leakage. With leakage comes fly ash debris around the boiler and localized flue gas condensation corrosion. While one soot blower port leaking may be minor, when multiplied by the number of soot
