How does superheater work in 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.
How a boiler works for steam?
In steam heating systems, a boiler furnace heats water by means of a gas or oil-fired burner and turns it into steam. The steam travels through pipes to radiators or convectors, which give off heat and warm the room. As the steam cools, it condenses back into water, and returns to the boiler to be heated again.
What is use of desuperheater in superheater?
The Basic use of a desuperheater is to minimize the temperature of superheated steam or other vapors. This temperature deduction is accomplished gives the process vapor being brought into direct contact with another liquid such as water.
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.
Which of the following enter the superheater of a boiler?
wet steam
Therefore, wet steam enters the super heater of a boiler, and thus the correct option is c).
How do you maintain steam heat?
How to Care for Your Steam Heating System
- Check the steam gauge regularly: Make sure that it’s within the normal range.
- Check the safety valve every month: Located on the top of the boiler, this important valve vents excess pressure if the boiler goes crazy and exceeds safe levels.
Can a steam boiler explode?
A steam explosion can occur in any kind of a water heater, where a sufficient amount of energy is delivered and the steam created exceeds the strength of the vessel. When the heat delivery is sufficiently rapid, a localized superheating can occur, resulting in a water hammer destroying the vessel.
How does desuperheater control the exit temperature from superheater?
When the desuperheater is operational, a measured amount of water is added to the superheated steam via a mixing arrangement within the desuperheater. As it enters the desuperheater, the cooling water evaporates by absorbing heat from the superheated steam. Consequently, the temperature of the steam is reduced.
What is economiser in 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.
