The cascading bypass system is perhaps the most common design for managing high-pressure steam in a combined-cycle plant. It is the hot reheat (HRH) bypass valve actuator that defines the valve’s ...
In August’s column, I discussed three-way control valves, their associated bypass pipes, and the importance of a balancing valve being located within the bypass pipe. Such balancing valves are needed ...
Combined-cycle power plants operate by integrating a combustion turbine generator (CTG) and heat recovery steam generator (HRSG) with a steam turbine generator (STG). However, during some modes of ...
