High-Pressure Steam Flow in Turbine Bypass Valve System Part 1: Valve …

WebThe turbine bypass system diverts the system flow around the steam turbine generator to the condenser, which provides the ultimate heat sink. This serves to drop the system pressure, while still passing sufficient flow to maintain HRSG superheater and reheater section cooling. The valves on this part of the system act as “ steam dump valves ” Webvalves. Turbine bypass values operate under the most severe conditions, reducing pressure from nearly 200 bar t 40 bar and temperatures ranging from 500°C to 150°C in a very short time interval of less than a second. The HP bypass valve type considered in this work is a stream-conditioning valve for stream throttling with very
