Achieving highest steam quality in HRSG systems
with iTHERM TwistWell thermowell design
By integrating a thermometer with iTHERM TwistWell thermowell with advanced helical design, operators can achieve superior steam quality and significantly reduce vortex-induced vibrations.
Benefits
Ensured pure steam quality from wet to superheated steam
Optimized heat exchange control
Good accuracy with short immersion length
Reduced process disruptions, no pressure drops
Right separation ratio of water/steam mixture in steam drums
The challenge
One of the primary challenges in HRSG systems is dealing with high-velocity steam, which can cause vortex-induced vibrations (VIV) and pressure drops around thermowells. Vortexes and pressure drops carry to undesired phase changes in the stream or unexpected changes of the steam/water ratio when the two phases must exist in the mixture. Ensuring the integrity and performance of the thermowell is therefore essential to maintaining system efficiency and safety.
Our solution
The thermometer iTHERM ModuLine TM151 / 152 (metric / imperial) with thermowell iTHERM ModuLine TT151 / TT152 (metric / imperial) features a specific Endress+Hauser innovation, our iTHERM TwistWell for high-velocity applications. The product design of iTHERM TwistWell is inspired by the common procedure for industrial chimneys, utilizing a helix geometry. This patented helical design drastically reduces vortex-induced vibrations (VIV) by more than 90%.
