What is a steam surface condenser?
A surface condenser is a water-cooled shell and tube heat exchanger installed to condense exhaust steam from a steam turbine in thermal power stations. These condensers are heat exchangers which convert steam from its gaseous to its liquid state at a pressure below atmospheric pressure.
Why condenser is used in steam power plant?
The main purpose in steam power plant is to generate maximum power at high efficiency. The most effective way for reaching this aim is to use a condenser. Condensers increase the enthalpy drops and turbine work by lowering the turbine outlet pressure. The lower the pressure, the higher the efficiency and power are.
Where is the surface condenser used?
Definition: Surface condensers are mainly used in large power plants and refrigeration systems. The main purpose is to condense the exhausted steam in order to obtain high efficiency and convert the steam into impurity-free water which can be used in a steam generator or steam boiler.
How does a steam condenser work?
Working of Steam Condenser: The steam condensers receive exhaust steam from one end and come into contact with the cooling water circulating within it from the cooling tower. As low-pressure steams comes in contacts with cold water, it condenses and transforms into water.
Which condenser is used in power plant?
A surface condenser or steam condenser is a water-cooled shell and tube heat exchanger used to condensate the exhaust steam from the steam turbine in thermal power stations: the steam is converted from gaseous to liquid state at a pressure level below atmospheric pressure.
What are the different types of steam condenser?
The steam condensers are broadly classified into two types:
- Surface condensers (or non-mixing type condensers). In surface condensers, there is no direct contact between the exhaust steam and the cooling water.
- Jet condensers (or mixing type condensers).
How does surface condenser work?
Basic working principle of a surface condenser is transfer of heat from a higher temperature body to a lower temperature body. In a surface condenser steam (high temperature body) liberates its heat to the cooling water tubes ( low temperature body). The process of heat transfer the hot steam gets converted to water.
What is the difference between surface condenser and tubular condenser?
There is not much difference in them from a basic standpoint. Both are “Shell & Tube Exchangers”. Both normally have Cooling Water in the Tubes and the commodity to be cooled in the Shell. The big difference is where they are located, their relative size, what they are associated with and what the Shell commodity is.
How does a surface condenser work?
What are the components of a steam power plant?
A steam power plant consists of a boiler, steam turbine and generator, and other auxiliaries. The boiler generates steam at high pressure and high temperature. The steam turbine converts the heat energy of steam into mechanical energy. The generator then converts the mechanical energy into electric power.
What is steam power plant?
Which condenser is more suitable for high power capacity plants?
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.
What is a surface condenser in a thermal power plant?
The surface condenser is one of the most important devices used in thermal power plants. If a surface condenser is not used in a thermal power plant, a large amount of water will be needed in order to run the plant.
What is a maarky steam surface condenser?
A steam surface condenser is a critical component of a power plant. The generating capacity of a power plant is dependent on the performance of the steam surface condenser. Maarky condensers are designed to provide the lowest backpressure which, in turn, maximizes the output from the power plant.
What is a steam condenser in a turbine?
A steam condenser is a closed vessel-type heat exchanger applied to convert low-pressure exhaust steam from the turbine to water. A steam condenser is a mechanical device employed to condense exhaust steam of the turbine into the water. It conducts this process with the help of cooling water that circulates inside it from the cooling tower.
What size power plant can steam condensers be used for?
Steam surface condensers are offered for power plants ranging in output from 10 MW to 1000 MW and in the following configurations: Each condenser is designed in accordance with the client’s specifications to offer the highest thermal efficiency and structural integrity.
