What is the function of superheater 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 purpose of economizer?
An economizer is a mechanical device used to reduce energy consumption. Economizers recycle energy produced within a system or leverage environmental temperature differences to achieve efficiency improvements.
What happens in a superheater?
In a steam engine, the superheater re-heats the steam generated by the boiler, increasing its thermal energy and decreasing the likelihood that it will condense inside the engine. Superheaters increase the thermal efficiency of the steam engine, and have been widely adopted.
What is the purpose of the superheater in a boiler?
A superheater is a vital part of the a boiler system that is used to increase the overall efficiency of a thermal power plant. More specifically, it is a device which converts wet steam (saturated steam) into dry steam as dry steam contains more thermal energy.
What is the purpose of superheater 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.
What is the purpose of superheater 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. 11.
Where is the economizer located in a boiler?
flue gas
They are heat exchanger coils‚ usually finned‚ that are located in the flue gas ducting at the exit of the boiler.
What is the purpose of economizer in water tube boiler?
The economizer also prevents flooding of the boiler with liquid water that is too cold to be boiled given the flow rates and design of the boiler. A common application of economizers in steam power plants is to capture the waste heat from boiler stack gases (flue gas) and transfer it to the boiler feedwater.
What is the purpose of economizer in the boiler?
Economizers are heat exchangers that transfer the heat in the flue gas to another medium‚ generally the boiler feed-water‚ although other streams are sometimes used such as make-up water. There are 2 types of economizers: non-condensing and condensing.
