What are the classification of condenser?
In high level jet condensers, the condensate falls to the hot well by the barometric leg provided in the condenser. Condensers are classified as follows: In jet condensers which is to be condensed. In surface conden the steam which is to be condens In parallel flow the same direction.
What do you mean by steam condenser?
Steam Condenser is a mechanical device which converts the low pressure exhaust steam from the turbine into water. Or in other words it is a device which is used to condense exhaust steam of the turbine into water. It does so with the help of cooling water circulated into it from the cooling tower.
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 condenser explain the type of condenser?
A condenser in simple terms is a cooling device. Every refrigeration system and power plant use condensers to condense refrigerant vapors or steam and is known as a heat rejector. Actually, it turns superheated and highly-pressurized vapor into a subcooled liquid.
What is the steam generation?
A steam generator is a device that uses a heat source to boil liquid water and convert it into its vapor phase, referred to as steam. The heat may be derived from the combustion of a fuel such as coal, petroleum fuel oil, natural gas, municipal waste or biomass, a nuclear fission reactor and other sources.
What is the pressure of steam condenser?
In a typical wet steam turbines, the exhausted steam condenses in the condenser and it is at a pressure well below atmospheric (absolute pressure of 0.008 MPa, which corresponds to 41.5°C). This steam is in a partially condensed state (point F), typically of a quality near 90%.
How is steam condensed in a jet condenser?
Jet condensers, in which cooling water comes in direct contact with the exhaust steam and the steam as a result is condensed. The condensing or cooling water is usually sprayed into the exhaust steam so that rapid condensation of the steam OCCU[S.
How does a counter flow steam condenser work?
A low-level or counter-flow jet condenser is shown in the figure. In these types of steam condenser, the cooling water enters at the top and sprayed through jets. The steam enters at the bottom and mixes with the fine spray of cooling water. A separate pump removes the condensate. The air is removed by an air pump separately from the top.
Which is the primary object of a condenser?
The primary objectof a condenser is to maintain a very low back pressure on the exhaust side of the piston of the steam engine or the rotor of the steam turbine. This enables the steam to expand to a greater extent which results in an increase in available energy for converting into mechanical work.
Why do we need a steam condenser in a power plant?
The condensed steam is known as condensate. The efficiency of the steam power plant is increased by the use of a condenser. The steam condenser is an essential component of all modern steam power plants. A steam condenser has the following two objectives:
