A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7-2,000 kPa or 1-290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
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 among 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 temperature and pressure operating conditions.
