Attemperator optimization for steam tube damage prevention in combined-cycle power station

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.
