What is the function of condenser in power plant?
In thermal power plants, the purpose of a surface condenser is to condense the exhaust steam from a steam turbine to obtain maximum efficiency, and also to convert the turbine exhaust steam into pure water (referred to as steam condensate) so that it may be reused in the steam generator or boiler as boiler feed water.
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.
What is the advantage of condensing the steam from a power plant?
The main advantages of incorporating a steam condenser in a steam power plant are as follows: It increases the efficiency of the power plant due to increased enthalpy drop. It reduces back pressure of the steam which results in more work output.
What is a plant condenser?
“ 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 is the function of condenser in thermal power plant Mcq?
Q. | The function of a condenser in a thermal power plant is……. |
---|---|
A. | To act as reservior to receive steam for turbine |
B. | To condense steam into condensate to be reused again |
C. | To create vaccum |
D. | All of the above |
What kind of energy is a condenser?
Energy stored in a capacitor is electrical potential energy, and it is thus related to the charge Q and voltage V on the capacitor.
What happens to steam in condenser?
It is used to condense the steam. The steam with low pressure delivers its heat to the coolant (here water from the cooling tower), and it converts into the water through the condensation process.
What are the advantages and disadvantages of installing a condenser in a steam power plant?
ADVANTAGES AND DISADVANTAGES OF A SURFACE CONDENSER
- The condensate can be used as boiler feed water.
- Cooling water of even poor quality can be used because the cooling water does not come in direct contact with steam.
- High vacuum (about 73.5 cm of Hg) can be obtained in the surface condenser.
- The capital cost is more.
Why only condenser is used in Rankine Cycle?
Originally Answered: why condenser is used in rankine cycle? Simply to increase the overall efficiency of Rankine cycle. The specific volume of steam is higher than the water.So by using condenser the steam get condensed and changes state to water.
What is a 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.
What is the purpose of condenser Mcq?
Explanation: Condensers use the property of condensation which is a convective heat transfer process that is associated with a change in the phase of a fluid from the gas to a liquid phase.
What is the purpose of a condenser in a thermal power plant?
Generally condenser is used for cooling. In thermal power plant the purpose of condenser is to convert the exit steam from turbine to water for pump.
What is the function of condensers in wind turbines?
The exhaust steam from the low pressure turbine enters the shell where it is cooled and converted to condensate (water) by flowing over the tubes. Such condensers use steam ejectors or rotary motor-driven exhausters for continuous removal of air and gases from the steam side to maintain vacuum.
What is the working principle of the condenser?
In the operation of the condenser, first of all we pull the vacuum in the condenser then we start the cooling water (CW) pump and then we charge condenser from the steam side.
How does high condenser vacuum improve power plant capacity?
High condenser vacuum improves power plant capacity. Condenser fouling leads to a decreased condenser vacuum which in turn affects the fuel conversion efficiency and leads to an output decrease or capacity decrease of the plant. When the condenser operates under a vacuum, it pulls the steam which improves overall performance of the turbine.
