the work of the condensor is to condense the hot steam and change its state so that it can be used again in boiler

A flow diagram of a steam condenser typically illustrates the process of condensing steam into water for reuse in a steam cycle. The diagram shows steam entering the condenser, where it comes into contact with cooling water, leading to heat exchange that cools the steam. As the steam condenses, it transforms into liquid water, which is then collected and often pumped back into the boiler. The cooling water, having absorbed the heat, is usually expelled or recycled back to a cooling system.
If you are talking about a condenser attached to a steam turbine, then a vacuum is important because it extends the usefulness of the steam in the turbine. As you probably know, steam begins to condense back into water at 212 deg at atmospheric pressure. However, in a vacuum condition, the boiling and condensing temperature is lower. Because the condenser is under a vacuum, steam exits the turbine and enters the condenser around 130 deg. This results in more power (mega watts).
A steam turbine condenser equipped with ejectors is usually fitted with two ejectors. The larger of the two is called the hogger and the smaller the huffer. Steam turbines are designed for efficiency and thus attempt to extract as much energy from the steam passing thru as is physically possible. Energy is extracted as both temperature and pressure decrease. The lower the temperature and pressure at the steam turbine's exhaust the more energy can be extracted from the steam. For this reason it is desirable for the steam turbine condenser (the exhaust) to be at the lowest temperature and pressure possible. The hogger, or hogging jet, is a large steam powered ejector that causes the steam condenser to operate under a near perfect vacuum whilst the steam turbine is in the start-up phase. In steady state operation the cooling effect of the condenser cooling water of the steam causes the condenser to operate under a nearly self sustained vacuum. The hogger is necessary in the start-up phase to prevent steam from condensing to water in the final stages of the turbine before the steam flow and cooling effect of the condenser can establish vacuum. The huffer or huffing jet runs continuously whilst the turbine is operating to remove any non-condensable gasses (i.e. air) that might leak into the condenser. It is nearly impossible to perfectly seal a condenser and turbine from air-in leakage. It should be noted that modern, large steam turbines do not employ steam ejectors to establish and maintain condenser vacuum. Modern designs utilize motor driven mechanical vacuum pumps.
gland condenser is a type of condenser in which steam which is coming from d turbine is used for the heating of demineralised water and then this water is sent to the boiler so boiling of hot water consumes less coal and thus we get benifit of it
It is important to maintain a vacuum in a condenser if you want it to work well.
James Watt did NOT get the steam engine to work - it already was. But he added a condenser and upped the efficacy by several times, making it a practical device.
A kenotometer is an instrument used in steam turbine condensers to measure the vacuum in the steam space of the condenser. The vacuum achieved by the condenser has significant influence on the efficiency of the steam turbine.

For increasing steam turbine efficiency. if vacuum is not maintained then, uncondensable gases and air in condenser will increase the condenser pressure.
The steam when cooled changes back to liquid water
