What happen if the vacuum inside the condenser increases?

When a vacuum exists in the condenser, atmospheric air will leak into the condenser shell through flanges and other leakage points raising the condenser pressure. Dissolved gas in the water used to raise the steam will also enter the condenser along with the steam, but will not condense.

Why vacuum is used in steam turbine?

In other words, it is impossible to prevent the entrance of air and other non-condensable gases into the condenser. A vacuum is maintained in the condenser so that steam can easily flow and more work can be extracted from the steam in the turbine; this is the reason why vacuum is maintained in condensers.

Why is it necessary to maintain high vacuum in a 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 are the reason for low vacuum?

The main factors for abrupt vacuum reduction are: full water in the condenser. halt of steam supply from the bearing seal. fault at the water jet pump. improper operation at the vacuum system valve.

How does steam create vacuum?

When matter turns from its gas phase back into its liquid phase, the molecules take up much less space and exert far less pressure. In fact, the condensing steam creates a partial vacuum—a region of much lower pressure than that of the surrounding atmosphere—inside the bottle.

What in the condenser will create a higher back pressure on the turbine loss of vacuum?

Lower Thermal Efficiency: The leaked air in the condenser results in increased back pressure on the turbine this means there is loss of heat drop consequently thermal efficiency of plant will decrease. So it requires more cooling water to condense more latent heat steam.

What happens in a vacuum physics?

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. It is a condition well below normal atmospheric pressure and is measured in units of pressure (the pascal).
