Boiler Waterwall Tubes and Condenser Tube Leakage

Tube failures are a cause of concern in boiler outage, contaminating boiler feed water due to condenser leakage leads to a large amount of damage. Condensers using brackish water for cooling in high pressure boilers will have to be maintained well to avoid any leakage of condenser tubes. Any leakage of condenser cooling water to the condensate leads to low pH levels in boiler water, which can
