Moisture Separator Reheaters – MSR

Our team of dedicated specialists manage every aspect of MSR projects—from uprate studies to design and testing to installation and user training. Independent of any turbine original equipment manufacturers ( OEM ), TEi collaborates with our clients to provide optimized MSR design solutions for any architectural configuration, inclusive of horizontal or vertical orientation, single or dual stage reheat, internal or external header and side or bottom inlet vessels. We have custom designed and supplied hardware for all imaginable configurations from internal upgrades of Reheater or Moisture Separator ( MS ) system designed for efficient installation into the existing shells to complete vessels for new and existing plants to meet and exceed thermal performance guarantees and thoroughly address all OEM design deficiencies ensuring lifetime, maintenance free operation.

• MSRs are the bridge between the High and Low-Pressure Turbines.
• No alternative flow path exists but through the large and unique, dual purpose heat exchangers.
• Consequently, an optimally designed MSR sourced from a proven supplier is fundamentally critical to the operability and heat rate efficiency of the Power Generating Function of Nuclear Power Stations.

• Minimize vessel weight (important for power uprates) by employing an elegant design void of extraneous flow discontinuities and eliminating complex, inefficient steam distribution systems
• Deliver Moisture Separation Efficiency ( MSE ) of virtually 100% to maximize High and Low Pressure Turbine Work Output and reduce Low Pressure Turbine maintenance due to premature onset of wetness.
• Minimize pressure drop enabling increased power ( MWe ) output
• Achieve highest attainable superheat outlet steam temperatures, improving plant heat rate and cycle efficiency
• Optimize excess steam consumption for stable operation and highest thermal efficiency
• Enhance durability with correct metallurgy by deploying corrosion and erosion resistant materials to high velocity, wet steam plenums

• Performance: Maximum Moisture Separation Efficiency (MSE) , Minimum Pressure Drop (dP), and Maximum Hot Reheat Superheated Steam temperature (TTD)
• Reliability: Advanced material selection and modern analytical design methods eliminate susceptibility to flow induced vibration damage mechanisms and proactively prevent thermal distortion induced structural failures
• Operability: Stable, consistent steam admission and condensate removal system operation with smooth, trouble free transient response
• Decades of Industry Leadership from a dedicated team of experts
• With over 150 complete MSR vessels supplied worldwide, and hundreds of upgrades completed, TEi’s technology has been operationally proven to improve plant heat rate and extend equipment life beyond the design basis of the plant. Our transcendent engineering expertise and commitment to quality ensure your plant operates at peak efficiency with enhanced reliability.
