Gland steam condenser in steam turbine sealing system

A gland steam condenser is a component of a steam turbine sealing system that is used to condense the steam that is used to seal the turbine shaft. The steam turbine sealing system is designed to prevent steam from leaking out of the turbine and to prevent air from entering the turbine.

The gland steam is a low-pressure steam that is used to seal the space between the rotor and stator of the turbine. This steam is supplied to the turbine through the gland seal, which is located at the end of the turbine shaft. The gland steam is typically supplied at a pressure of around 1-2 bar and a temperature of around 120-150°C.

The gland steam condenser is located in the low-pressure area of the turbine, and it is used to condense the gland steam before it is discharged to the atmosphere. The condenser typically consists of a shell and tube heat exchanger, where the steam is condensed by circulating cooling water through the tubes.

The condenser operates by passing the gland steam through the tubes, while cooling water flows through the shell side of the heat exchanger. As the steam passes through the tubes, it transfers its heat to the cooling water, which causes it to condense into water. The condensed water is then discharged from the bottom of the condenser.

The gland steam condenser helps to maintain the proper pressure in the sealing system, which is necessary for the proper operation of the turbine. If the pressure in the sealing system is too high, it can cause steam leakage and reduce the efficiency of the turbine. If the pressure in the sealing system is too low, it can cause air to enter the turbine and reduce its performance.

Overall, the gland steam condenser is an essential component of the steam turbine sealing system, as it helps to maintain the proper pressure and prevent steam leakage. Proper design, installation, and maintenance of the gland steam condenser are critical to ensuring the optimal performance of the turbine.
