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.

How is steam condensed in a condenser?

A condensing steam turbine is provided with a vacuum device at its exit (the condenser) where the forced flow of an external coolant (water or air) maintains the outlet pressure at a level dependent only on the coolant inlet and outlet temperatures.

What are the parts of steam condensing plant?

Elements of a Condensing Plant

• Condenser. The condenser is a closed vessel in which steam is condensed.
• Condensate Pump. It is a pump, which removes condensate (i.e. condensed steam) from a condenser to a hot well.
• Hot Well.
• Boiler Feed Pump.
• Air Extraction Pump.
• Cooling Tower.
• Cooling Water Pump.

What is steam condenser and its types?

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).

What happens when steam is condensed class 7?

Solution : The process of change from gaseous to liquid phase is called condensation. Steam (water in gaseous state) after condensation yields water (liquid state).

Why is steam condensed?

Without heat, the water molecules inside the bottle start condensing—that is, they start turning from steam back into liquid water. When matter turns from its gas phase back into its liquid phase, the molecules take up much less space and exert far less pressure.

What are the advantages of condenser?

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.

Why do we use condenser?

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.

What is a steam condenser?

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 at the turbine into the water. It conducts this process with the help of cooling water that circulates inside it from the cooling tower.

Which way does the steam flow in a jet condenser?

In counter Flow or low level jet condensers, the steam enters at the bottom and the cooling water at the top. The steam flows upward and meets the cooling water coming downward.

How is condensation done in steam engines?

Condensation can be done by removing heat from exhaust steam using circulating cooling water. During condensation, the working substance (steam) changes its phase from vapour to liquid and rejects latent heat as shown in Figure 1.

What is the working principle of the low pressure steam condenser?

As the low-pressure steam comes in contact with the cooling water, it condenses and converts into water. It is connected to the air extraction pump and condensate extraction pump.
