What is the benefit of using superheated steam?
Advantages of using superheated steam to drive turbines: It is advantageous to both supply and discharge the steam while in the superheated state because condensate will not be generated inside steam-driven equipment during normal operation, minimizing the risk of damage from erosion or carbonic acid corrosion.
What is a super heater in a boiler?
Superheaters and reheaters are specially designed to increase the temperature of the saturated steam and to help control the steam outlet temperature. They are simple single-phase heat exchangers with steam flowing inside and the flue gas passing outside, generally in the cross flow.
Which of the following is heated by using super heater?
Super heater is a component of the boiler (used for heating: liquid, steam, etc.). It is a coiled heat exchanger that heats the steam to produce super – heated steam. It converts wet steam produced by a boiler to dry stream.
What is the purpose of super heater in a boiler Mcq?
Explanation: function of the superheater is to increase the temperature of steam above its saturation temperature. as heat contained in unit mass of superheated steam is more than dry saturated or wet steam, it is extensively used in steam power plants.
What is the difference between saturated and superheated steam?
Saturated steam is steam that is in equilibrium with heated water at the same pressure, i.e., it has not been heated above the boiling point for its pressure. This is in contrast to superheated steam, in which the steam (vapor) has been separated from the water droplets then additional heat has been added.
What is the difference between boiler and super heater?
It is different from a boiler in a way that, boiler utilizes both sensible heat as well as latent heat to convert water into steam while superheater utilizes only sensible heat to superheat the steam in order to increase its enthalpy.
What is the function of super heater and economizer?
Since the super heater steam has a lot of energy the super heater is used for reduce the temperature of the steam, the economizer helps in minimizing the conservation of energy and re-heater is used for increasing the thermal efficiency of the boilers.
What is the function air heater in the boiler?
Air Pre-heaters are basically heat-exchangers installed in the exit flus gas duct of the boiler. The purpose of the air preheater is to recover the heat from the boiler flue gas which increases the thermal efficiency of the boiler by reducing the useful heat lost in the flue gas.
Is the steam generated in the boiler drum saturated or super heated?
Saturated steam is used for efficient and effective heat transfer across many industries. Meanwhile, superheated steam is created when saturated steam flows out of the drum of the boiler and into a secondary heating area called a superheater.
What is the function air heater in the boiler Mcq?
11. What is the function Air heater in the boiler? Explanation: Function of air preheater is to recover the heat of a portion of exhaust flue gases before the flue gases enter the chimney. It is places along the passage of the exhaust flue gases in between the economizer and the chimney.
