Why it matters
Key Benefits
Maintained Condenser Performance
Condenser tube condition monitoring and leak detection maintains condenser vacuum and prevents cooling water ingress that contaminates the feedwater cycle and damages boiler tubes.
Reliable Feedwater Heater Operation
Feedwater heater performance trending and tube integrity assessment ensures extraction steam heating raises feedwater temperature to the levels that boiler efficiency and heat rate optimization require.
Protected Lube Oil and Auxiliary Cooling
Lube oil cooler and generator hydrogen cooler monitoring ensures adequate heat rejection for the turbine-generator bearing and winding cooling systems that equipment protection depends on.
Context
Challenge & Approach
The Reliability Challenge
Power plant feedwater heaters experience tube erosion-corrosion from high-velocity, high-temperature feedwater and steam impingement on tube bundles near desuperheating zones. Condenser tube fouling from circulating water biological growth, silt deposition, and scaling increases backpressure and degrades heat rate. Tube leaks in feedwater heaters allow cold water ingress that reduces feedwater temperature and increases boiler heat input requirements. Condenser tube failures allow cooling water into the steam cycle, contaminating boiler water chemistry. Heat rate degradation from fouled feedwater heaters and condensers directly increases fuel costs per MWh generated.
Our Approach
We perform thermal performance analysis using terminal temperature difference (TTD) and drain cooler approach (DCA) calculations to quantify feedwater heater degradation. Condenser performance analysis using cleanliness factors and backpressure trending identifies fouling impact on heat rate. Eddy current tube inspection detects wall thinning, pitting, and cracking. We evaluate tube plugging patterns and remaining tube margin for each exchanger. Our deliverable includes a heat rate impact analysis of exchanger degradation, tube condition assessment, condenser cleaning optimization schedule, feedwater heater performance trend, and a tube replacement planning timeline integrated with unit outage scheduling.

Learn More →Condenser tube leaks introduce cooling water (which contains dissolved solids, chlorides, and treatment chemicals) into the highly purified condensate. Even small leaks raise conductivity, increase dissolved oxygen, and introduce chlorides that cause boiler tube pitting and stress corrosion cracking. Condenser water chemistry monitoring provides continuous leak detection, and the affected waterbox must be isolated for leak identification and tube plugging to protect the boiler.
Feedwater heater tube failures result from erosion-corrosion in carbon steel tubes at areas of high-velocity two-phase flow, stress corrosion cracking in stainless steel tubes exposed to chloride concentrations from condenser leaks, vibration fatigue from insufficient tube support at baffle locations, and thermal fatigue at the desuperheating zone where high-temperature extraction steam contacts the tubes. The dominant mechanism depends on heater type, tube material, and operating conditions.
Eddy current tube inspection should be performed during major planned outages (typically every 2 to 4 years) to establish tube wall condition and degradation rates. Condenser tube leak detection monitoring should be continuous using conductivity instruments on each waterbox hotwell. Plants with known tube degradation issues may inspect annually. The inspection frequency depends on tube material, cooling water quality, and the historical tube failure rate.
