Heat-Recovery Steam Generators: Understand the Basics

reasonable pressure drop in the super-heater, we can determine the saturation temperature (t s) at the evaporator. Once the pinch point is selected, we know the temperature of the gas leav-ing the evaporator(t g3) and the ap - proach point gives the temperature of the water leaving the economizer (tw2), since the saturation temperature is known.

What is a Superheater? (with pictures)

Parker Brown. A superheater may be found in steam boilers. A superheater is a device found in steam boilers that is used to convert wet, saturated steam into dry steam. Superheaters are a very beneficial part of the steam cycle, because dry steam contains more thermal energy and increases the overall efficiency of the cycle.
