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. In a boiling-water reactor, it returns to the reactor core.
What is the role of the condenser in a nuclear power plant?
The Condenser has two major functions: Condense and recover the steam that passes through the turbine (Condensers are used in all power plants that use steam as the driving force) Maintain a vacuum to optimize the efficiency of the turbine.
Why do we use condenser?
The function of the condenser in a refrigeration system is to transfer heat from the refrigerant to another medium, such as air and/or water. By rejecting heat, the gaseous refrigerant condenses to liquid inside the condenser.
How does a condenser work in thermal power plant?
A thermal power station converts heat energy to electric power via steam-driven turbine: heated water turns into steam and drives a steam turbine connected to an electrical generator. After passing through the turbine, the steam is condensed in the condenser and recycled to the boiler for reheating and evaporation.
What is main condenser?
The main steam condenser (MC) system is designed to condense and deaerate the exhaust steam from the main turbine and provide a heat sink for the turbine bypass system. The exhausted steam from the LP turbines is condensed by passing over tubes containing water from the cooling system.
Why it is called surface condenser?
It is called the surface condenser because the exhausted steam and cooling water does not mix up.
When air is removed in a surface condenser what happens?
The prevention of leakage of air in the surface condenser is difficult because of the presence of the high vacuum in the condenser. (2) The air leakage results in lowering the partial pressure of the steam and temperature. This naturally results into increase in latent heat and hence more cooling water is required.
What are the three functions of a condenser?
This article will introduce you to the three key jobs performed by an air conditioner’s condenser.
- Desuperheating. Refrigerant exits your evaporator coil as a gas, having absorbed heat from inside of your home. …
- Condensation. …
What is condenser and how it works?
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.
What are the advantages of using condenser in a steam power plant?
Advantages of a condenser in a steam power plant
It reduces back pressure of the steam which results in more work output. It reduces temperature of the exhaust steam which also results in more work output. The condensed steam can be reused as feed water for boiler which reduces the cost of power generation.
What is the purpose of using condensers in refrigeration and in power plants?
In refrigeration operations, condensers are used to liquefy the high-pressure refrigerant vapor leaving the compressor. Heat exchangers referred to as surface condensers are used to condense the exhaust from steam turbines that generate in-house power for plant operations.
How does condenser tube work?
A typical condenser consists of a glass tube nested within another. Water flows between these two tubes. A chemist attaches the condenser to the top of a flask so that as refluxing solvent evaporates and travels up through the center tube, the flowing water cools the solvent.
What are the elements of a condensing plant?
Elements or Components of Condensing Plant:
- Air Extraction Pump.
- Condensate Extraction Pump.
- Cooling Water Circulating Pump.
- Hot Well.
- Cooling Tower.
- Boiler Feed Pump.
- Makeup Water Pump.
