TBS Turbine Bypass System

Description:
The Valvtechnologies Turbine By-Pass System (TBS) is designed for the new generation of combined-cycle power plants. It combines the Xactrol™ control valve design with a state-of-the-art de-superheating control system. The system allows the plant operator to keep the gas turbine and the HRSG on line in the event of a steam turbine trip. The TBS also facilitates fast CT and HRSG start-ups in peaking power plants, and allows these plants to operate at turndow conditions far below the levels that can be achieved.
