Fuel Storage & Distribution
Reliable fuel gas control for flexible turbine operation
As combined cycle plants cycle more frequently, fuel gas quality, pressure stability, and response time become critical to combustion turbine performance. Inconsistent fuel delivery can lead to turbine trips, efficiency losses, and increased maintenance.
Heat Recovery Steam Generator (HRSG)
Precise steam control under high thermal stress
In flexible CCPP operation, HRSGs are exposed to rapid temperature changes, frequent startups and shutdowns, and increased thermal fatigue driven by cycling duty. Accurate control of drum level, steam temperature, and pressure is essential to protect equipment and maintain efficiency.
Steam Turbine
Protecting performance and availability of critical assets
Steam turbines represent one of the most critical and valuable assets in a CCPP, with performance and availability directly impacted by final control reliability. As plants age and operating profiles change, reliable isolation, bypass control, and pressure protection become increasingly important.
Balance of Plant
Optimizing auxiliary systems for long term reliability
Beyond turbines and HRSGs, balance of plant systems - including condensate, feedwater, cooling water and auxiliary processes - play a crucial role in overall combined cycle power plant performance. Inefficient or failing auxiliary equipment can lead to forced outages, reduced plant availability, and increased operating costs.

Frequently Asked Questions
A combined cycle power plant (CCPP) is a power generation facility that produces electricity using both gas and steam turbines in a single integrated process, allowing waste heat from the gas turbine to be recovered and converted into additional power. This configuration delivers higher efficiency and lower emissions than conventional power plants and supports flexible, reliable power generation in Europe.
In Europe, CCPPs support the integration of renewables by enabling fast ramp‑up, frequent power plant cycling operation, and grid stability, while maintaining a lower carbon footprint than coal‑fired plants.
European CCPP operators face increased cycling operations, higher thermal and mechanical stress, stricter environmental regulations, and aging assets. These challenges require highly reliable control valves for power plants designed for demanding cycling conditions.
Control valves for power plants directly impact plant availability, efficiency, and safety. Poor valve performance can lead to unplanned outages, excessive noise, cavitation, and increased maintenance costs, especially during cycling operation.
Fuel gas and combustion turbine systems typically use fuel gas control valves and regulators from the Fisher™ portfolio, combined with digital valve controllers such as FIELDVUE™ to ensure precise fuel control, fast response, and continuous valve diagnostics.
Emerson addresses cavitation and noise in combined cycle power plants using Fisher™ anti‑cavitation trims and advanced noise‑attenuation valve technologies designed for high‑energy, cycling service. These solutions protect equipment, reduce vibration, and improve the reliability of control valves for power plants operating under high pressure and cycling conditions.
For HRSG and steam turbine systems, Emerson provides high‑performance steam control valves, desuperheaters, and Sempell™ steam isolation valves. These solutions support stable steam conditions, efficient heat recovery, and long‑term reliability.
In combined cycle power plants, digital valve controllers such as Emerson’s FIELDVUE™ enable predictive diagnostics and real‑time valve performance monitoring. They help operators detect valve issues early, reduce unplanned downtime, and optimize maintenance in cycling power plants.
