5.1 FOSSIL FUEL STEAM GENERATORS

Steam generator is a closed vessel that is used to generate steam at constant pressure as per the process requirement. The steam generated may be wet, dry saturated or superheated in state. In modern power plants, it is very common to use one boiler (single unit) per turbine, which leads to simpler piping systems and relatively easier boiler and turbine control. These boilers are usually designed to operate either at critical ...
