Tube Sheet Testing
Most condenser water sources contain dissolved solids that can precipitate and become deposited on the inner surfaces of the tubes and adversely affect the unit heat rate and limit generation capacity. Tube fouling can also prevent the turbine from generating its design load capacity. Tube sheet leak testing and the removal of accumulated deposits can recover a significant amount of lost output–up to 20MW in some cases.
Water In-leakage Testing
Water in-leakage can result from leaks in tube walls, leaks from joints between tube sheets and tubes ,and leaks between the water box and condenser shell. Contaminants in the condensate can cause corrosion in boilers, feed water heaters & steam generators and lead to stress corrosion cracking of turbine components. Quick and efficient leak detection and repair saves revenue by reducing unit downtime.
Air In-leakage Testing
Condenser air-inleakage causes a loss of vacuum in the system and an increase in back pressure, affecting heat rate and reducing generation capacity. Helium Leak Testing can quickly locate these leaks for repair and generate significant cost savings. High air in-leakage can often increase the concentration of dissolved oxygen in the condensate. This can increase the corrosion of feed heaters, boilers and steam generators.
