A. Heat air.B. Heat steam.C. Heat feed water.D. control steam.Answer: B. Heat steam.
Explanation: Functions of super heater in a thermal power plant are mentioned below :- The super heater repeats the heat processing system in the steam engine due to the steam generated by the boiler.
- The steam produced in the boiler is wet and is passed through a super heater where it is dried and superheated by the flue gases on their way to the chimney.
- Superheating provides two principal benefits. Firstly, the overall efficiency is increased.
- Secondly, too much condensation in the last stages of the turbine is avoided.
- The superheated steam from the super heater is fed to the steam turbine through the main valve.
- Hereby further it increases the thermal energy.
- These are used to convert wet steam into dry steam.
- In most of the cases it increases the thermal efficiency of the steam engine.
- Steam produced from a boiler without a super heater will either be dry saturated or more likely, wet.
- In works where steam is transmitted over long distances, the Inevitable heat loss from pipe surfaces causes the steam to become even wetter at the point of use unless a super heater is fitted to the boiler plant.
-
This is a separate battery of pipes placed near the boiler furnace through which steam passes to receive additional heat by either convection or radiation.
- The super heater increases the surface area capable of accepting heat and the production of heat also slightly increases the thermal efficiency of the boiler.
