Gas turbines

Gas turbines should operate efficiently at highest reliability and safety. Gas turbines should produce electricity as clean and environmental friendly as possible.

High capacity, accurate control and safety

The major challenges in power production, also in Gas Turbine power production are:

Fuel economy, what is the fuel cost per produced kWh, the lower the better.

Availability, the more the gas turbine power plant is in operation, more it produces. The unplanned shutdowns should be avoided.

Global warming, the environmental regulations concerning the emissions are getting tighter and tighter, putting also pressure to gas turbine technology.

Health and safety, always important when rotating machines.

High performance valves

Metso’s comprehensive valve offering provide for each type of Gas Turbine an ideal solution with butterfly valves for blow off application, blade air cooling application and for fuel gas trip valves application. Neles butterfly provides high capacity with less pressure loss. On the fuel gas control valves application, Neles control valves provides the highest rangeability and control accuracy.

All valves are capable for very fast stroking in case of trip situation.

Significant savings through high capacity

Our high performance butterfly valves with 2-shaft design and special disc shape offers an outstanding capacity, that provides a possibility to reduce pipeline diameter compared to single shaft designs. Full metal seat design provides low torque leading to a compact, light unit with small actuators compared to other seat types.
