What is a Superheater? (with pictures) - wisegeek.com

Mar 30, 2019· 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. Not only that, dry steam also is less likely to condense within the cylinders of a reciprocating engine or the casing of a steam

convection cage walls and superheater I to IV, which dry and superheat the saturated steam. Superheater I is located in the back pass and superheater II after SH I. SH II is similar construction to superheater I. Final superheating takes place in superheater III and IV, which are Intrex type and lo-cated in the return legs of the boiler.

What is the different between radiant and convection

Apr 04, 2018· Simple logic to differentiate Radiant and Convection superheater is depend on the location of superheater in the boiler. A radiant superheater is placed directly in the combustion chamber. Simply we can say that radiant superheater can see the flames from burner. A convection superheater is located in the path of the hot gases.

Boiler | Engaged in Thermodynamics

Superheaters extract all of the liquid water from the steam by raising the temperature of the steam well above the saturation point. The superheater uses the additional energy to heat the steam exiting the boiler. The superheater, which contains horizontally or vertically oriented tubes, is suspended in a convective or radiative zone of the boiler.
