Quick Answer: What Is The Importance Of Condenser?

What is the difference between jet condenser and surface condenser?

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).

In jet condensers there is direct contact between the exhaust steam and cooling water..

How vacuum is created in condenser?

So the condenser has such a vacuum and takes exhausted steam from the turbine and gives condensate for feeding back to the boiler; and thus any additional partial pressure of air hinders condensation, as wasteful collisions between the two kinds of molecules develop a thermal barrier, between the steam and and cooling …

What is the difference between a compressor and a condenser?

The gaseous refrigerant moves to the outdoor unit. Condenser coils in the outdoor unit house the refrigerant during its return to liquid form. The compressor increases pressure on the gas, causing it to condense into liquid. As the refrigerant changes state, it release the heat it contains.

How do you calculate condenser capacity?

Condenser capacities (for 60 Hz) are located in Table 4. These capacities are given in MBH/°TD. Convert the THR calculated in step 2 to MBH/°F TD by dividing by 1,000 to get THR in MBH. Then divide the THR by the design TD to get MBH/°F TD.

What is the purpose of condenser in distillation?

In a distillation, liquid compounds can be separated from one another based on differences in boiling points of the liquids in a mixture. The purpose of the condenser is to cool the vapors of the components of the mixture, allowing them to condense to liquid form and be collected.

How does a surface condenser work?

A surface condenser is a commonly used term for 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.

What is the principle of condenser?

The purpose of the condenser is to receive the high-pressure gas from the compressor and convert this gas to a liquid. It does it by heat transfer, or the principle that heat will always move from a warmer to a cooler substance.

What is an example of a vacuum?

The definition of a vacuum is a space devoid of air or matter, or a tool that uses suction to clean. An example of a vacuum is a space with nothing in it. An example of a vacuum is something used to clean up dirt on a floor.

How does the condenser work in simple distillation?

During distillation, vapors are formed in the heated distillation flask. The condenser cools these vapors condensing them back to liquid droplets that flow down the condenser into the receiver flask.

What is the purpose of vacuum?

A vacuum cleaner, also known simply as a vacuum or a hoover, is a device that causes suction in order to remove debris from floors, upholstery, draperies and other surfaces. It is generally electrically driven. The debris is collected by either a dustbag or a cyclone for later disposal.

Why is a reflux condenser used?

A condenser is attached to the boiling flask and is clamped in an upright postion, the “reflux position”, and cooling water is circulated to cause the vapours to condense as they rise up the condenser and thus prevent them from escaping.

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 use of condenser in aircraft?

Aviation Glossary – Condenser. The component in a vapor-cycle cooling system in which the heat taken from the aircraft cabin is given up to the ambient air outside the aircraft. An electrical component, formerly called a condenser, that consists of two large-area conductors, called plates, separated by an insulator.

How vacuum is created?

Vacuum, space in which there is no matter or in which the pressure is so low that any particles in the space do not affect any processes being carried on there. … A vacuum can be created by removing air from a space using a vacuum pump or by reducing the pressure using a fast flow of fluid, as in Bernoulli’s principle.

How does an air cooled condenser work?

An air cooled condenser (ACC) is a direct dry cooling system where steam is condensed inside air-cooled finned tubes. … Since the steam coming from the turbine is at a low pressure, the ACC works at a pressure close to a vacuum, and non-condensable gases (G) are removed continuously by an air evacuation unit.

What is the purpose of distillation?

Distillation is used to purify a compound by separating it from a non-volatile or less-volatile material. Because different compounds often have different boiling points, the components often separate from a mixture when the mixture is distilled.

What is the meaning of condenser?

In systems involving heat transfer, a condenser is a device or unit used to condense a gaseous substance into a liquid state through cooling. … Condensers are used in air conditioning, industrial chemical processes such as distillation, steam power plants and other heat-exchange systems.
