SUPERHEATER

 SUPERHEATER

• The function of the super heater is to remove the last trash of moisture from the saturated steam leaving the boiler tubes and also increases its temperature above the saturation temperature.

• For this purpose the heat of the combustion gases from the furnace is utilized.

• Super heated steam is that steam which contains more heat than the saturated steam at the same pressure. The additional heat provide more energy to the turbine hence power out put is more.

• Superheated steam causes lesser erosion of the turbine blades and can be transmitted for longer distance with little heat loss

• A superheater may be convention type, radiant type or combination. However ,convention superheaters are more commonly used.
