What is the working of superheater?

A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, steam engines, and in processes such as steam reforming.

What is the role of superheater in a thermal power station?

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.

What is the function of economizer?

Economizers are mechanical devices intended to reduce energy consumption or perform a useful function such as preheating a fluid. In basic terms, an economizer is a heat exchanger.

What is the function of a superheater 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. 11.

What is the function of air preheater and superheater?

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.

How many types of economizers are there?

2 types
There are 2 types of economizers: non-condensing and condensing.

What is the function of superheater in the boiler co4 l2 *?

Explanation: Function of the superheater is to increase the temperature of steam above its saturation temperature.

What is working principle of steam turbine?

In simple terms, a steam turbine works by using a heat source (gas, coal, nuclear, solar) to heat water to extremely high temperatures until it is converted into steam. The potential energy of the steam is thus turned into kinetic energy in the rotating turbine’s blades.

What is a superheater used for?

A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, steam engines, and in processes such as steam reforming.

What is a super-heater in a steam turbine?

In a steam turbine, super-heated steam is used to rotate the turbine. The wet and saturated steam is supplied to the super-heater. And it is a device that converts it into dry and superheated steam. The super-heater’s temperature is the highest among all components of the thermal power plant.

How does a steam convection superheater work?

The headers are baffled so that the steam is made to pass back and forth through the connecting tubes, which carry their proportioned amount of steam, the steam Convection superheater absorbed heat mainly by the impingement of flow of hot gas around the tubes . A purely convection superheater has a raising steam temperature characteristics.

Why are superheaters not used in nuclear power plants?

Since the temperature of the primary coolant is limited by the pressure inside the reactor, superheaters (except a moisture separator reheater) are not used in nuclear power plants and they operate usually a single wet steam turbine.
