Why condenser is used in chemistry?
In chemistry, a condenser is laboratory apparatus used to condense vapors — that is, turn them into liquids — by cooling them down. Condensers are routinely used in laboratory operations such as distillation, reflux, and extraction.
Why condenser is used 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.
Where are condenser used?
Today, capacitors are widely used in electronic circuits for blocking direct current while allowing alternating current to pass. In analog filter networks, they smooth the output of power supplies. In resonant circuits they tune radios to particular frequencies.
Why is condenser used in the distillation process?
Condenser is a cooling unit used in the distillation process. For cooling the vapors back to liquid droplets the condenser is fitted. Hence we can say that the main aim of the condenser is to cool the vapors, release heat to the surroundings and collect the liquid back through the condensation process.
Why is a condenser called a condenser?
Capacitors and capacitors are components used in electrical circuits that can store charge. it is called a condenser because its function is similar to that of the “mechanical condenser” which converts a large vapor into a smaller volume of liquid.
What is the liquid that leaves the condenser called?
As the refrigerant leaves the condenser, it is cooler, but still under pressure provided by the compressor. It then reaches the expansion valve. The expansion valve allows the high-pressure refrigerant to “flash” through becoming a lower pressure, cooled liquid.
Why do we use economiser?
An economizer is a mechanical device used to reduce energy consumption. Economizers recycle energy produced within a system or leverage environmental temperature differences to achieve efficiency improvements.
Why do we need vacuum in condenser?
The removal of air and other noncondensable gases from the condenser shell side is required for proper heat transfer from steam to cooling water in the condenser and, thus, to maintain high vacuum in the condenser.
What is the principle of condenser?
Principle of operation 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.
Why capacitor is called condenser?
The capacitor was initially known as a condenser. The term “condensor” was associated with it because it was supposed to condense electric charge. The charge it could hold at a rated voltage was known as “capacity.” This term was in use till about 1960s.
What is condenser Class 9?
When a homogeneous mixture of solid and a liquid is heated in a closed distillation flask, the liquid, being volatile, forms vapour. The vapours of liquid are passed through a “condenser” or “Liebig condenser” where they get cooled and condense to form pure liquid.
Why is a condenser used in distillation process Class 11?
Answer: Condensers are used in distillation to cool the hot vapors, condensing them into liquid for separate collection. For fractional distillation, an air or Vigreux condenser is usually used to slow the rate at which the hot vapors rise, giving a better separation between the different components in the distillate.
When does a total condenser need to be used?
A total condenser is used, when the available cooling water temperature is sufficient to condense all the condensable vapor that is generated at column overhead. This is calculated by finding out first the bubble point of the mixture that is expected at column overhead.
What is the role of a condenser in a power plant?
(1)The first objective is to create a low back pressure (vacuum) at the turbine exhaust so as to obtain the maximum possible energy conversion from the high pressure and high temperature steam and thus to increase the efficiency of the power plant.
Why does a condenser have to keep the temperature low?
As the vapor condenses, it releases the corresponding heat of vaporization, that tends to raise the temperature of the condenser’s inner surface. Therefore, a condenser must be able to remove that heat energy quickly enough to keep the temperature low enough, at the maximum rate of condensation that is expected to occur.
How is a condenser used in a steam turbine?
A condenser is used to convert the steam from the exit of the turbine to saturated liquid. This is done so that we can use a pump to pressurize the liquid. There is no mechanical device till date which can work on steam+liquid mixture.
