Attemperator optimization for steam tube damage prevention in combined-cycle power station
Attemperator optimization with clamp-on ultrasonic flow measurement, for the prevention of steam tube damage in a combined-cycle power station
Optimizing attemperators to prevent steam tube damage
Combined-cycle power stations (CCP) are pivotal in the energy sector, offering high efficiency and flexibility. Yet, this flexibility brings challenges, such as maintaining steam tube integrity. A leading US power producer faced issues with HP attemperator spray lines cracking due to undetected valve leak-by, causing thermal fatigue. Traditional monitoring methods fell short, especially under low flow conditions, prompting a search for a better, maintenance-free solution that would not interrupt processes.

Product Solutions
The portable Flexim FLUXUS F601 Energy is specially designed for temporary heating and cooling Thermal Energy measurement, with all measurements - Flowmeter, Temperature, and BTU computer, contained in one device. Temperature and BTU calculations are done in accordance with EN 1434 Thermal Energy meter standard. The F601 Energy measures the volumetric flow rate non-intrusively via its clamp-on ultrasonic transducers. Simultaneously, temperature probes monitor the temperatures at the supply and return lines of the heating or cooling system. From the temperature difference as well as the measured volume flow rate and the physical media parameters (liquid enthalpy data stored in the meter), the heating or cooling performance is calculated.
- Portable and non-intrusive flow and thermal energy meter for liquids.
- Non-intrusive measurement for precise bi-directional thermal energy flow rates.
- Ideal for inner pipe diameters ranging from DN6 to DN6000.
