What is condenser in power plant?
What is condenser in power plant?
A large heat exchanger designed to cool exhaust steam from a turbine below the boiling point so that it can be returned to the heat source as water. In a pressurized-water reactor, the water is returned to the steam generator.
What is condenser PDF?
The Condenser removes the heat from refrigerant carried from evaporator and added by compressor and converts the vapour refrigerant into liquid refrigerant. ∎ It is an Heat Exchanger in which heat transfer takes place from high temperature vapour to a low temperature liquid with help of cooling like air or water.
What is the principle of condenser?
Principle of operation A condenser is designed to transfer heat from a working fluid (e.g. water in a steam power plant) to a secondary fluid or the surrounding air. The condenser relies on the efficient heat transfer that occurs during phase changes, in this case during the condensation of a vapor into a liquid.
Which condenser is more suitable for high power capacity plants?
3.5. The surface condenser is the type most commonly used in modern power plants and hence it will be the only one taken into consideration. Here, the main heat transfer takes place at the outside of the tube, thereby cooling vis-a-vis condensing of the saturated steam, and hence heating of the CW inside the tube.
Why is a condenser used?
Condensers are used for efficient heat rejection in many industrial systems. Condensers are used in air conditioning, industrial chemical processes such as distillation, steam power plants and other heat-exchange systems. Use of cooling water or surrounding air as the coolant is common in many condensers.
Why is the evaporator used?
An evaporator is a device used in a process to turn the liquid form of a chemical substance, such as water, into its gaseous form – vapor. The liquid is evaporated, or vaporized, into a gas form of the targeted substance in that process.
What is double condenser?
Double tube condensers have a tube of water inside a large refrigerant tube. The water absorbs most of the refrigerant heat, but as the refrigerant tube is in contact with the natural circulation of air, part of the cooling process is on natural convection.
What is condenser capacity?
The condenser capacity is the ability of the condenser to transfer heat from the hot vapour refrigerant to the condensing medium. As the temperature difference increases, the heat transfers rate increases and therefore the condenser capacity increases.
