As power generating facilities swing their output to meet varying demand, they place additional requirements on the turbine bypass valves. The bypass function requires valves to quickly and accurately change load on the turbine during startup, emergency or clean-up situations.
Turbines and boiler tubes are generally amongst the single highest cost assets within a power generation facility, and for this reason, these assets must be protected from operation outside the normal process operating conditions in terms of temperature and pressure. During startup, or turbine trip conditions, steam turbines require the use of the main steam bypass systems to protect equipment from thermal shock or second phase flow.
Fisher’s Steam Conditioning valves, supplied by Spartan, allow for efficient turbine bypass for startup by reducing pressure and temperature of the bypass steam in a single device. Improve lifetime cost savings, increase efficiency, and avoid turbine trips and unplanned down time by utilizing Spartan’s Steam System Control solution.
