Now keep gas turbine and heat recovery system generator (HRSG) online in the event of a steam turbine trip with the ValvTechnologies’ turbine bypass system (TBS). Purposefully designed for the new generation of combined-cycle power plants, our TBS combines the proven XactrolL® severe service control valve design with a state-of-the-art de-superheating control system. At the same time, the TBS facilitates fast HRSG and CT start-ups in peaking power plants. and helps these plants operate at turndown conditions far below the levels that can be achieved with standard governor systems.
