What does a gland steam condenser do?
The gland steam condenser receives steam and noncondensable gases from the TGSS and condenses the steam. Air and non-condensable gases are evacuated from the gland steam condenser and discharged into the air vent system by exhaust fans.
How does a steam turbine condenser work?
By condensing the exhaust steam of a turbine at a pressure below atmospheric pressure, the steam pressure drop between the inlet and exhaust of the turbine is increased, which increases the amount of heat available for conversion to mechanical power.
What is condensing steam turbine?
Condensing steam turbines are most commonly found in thermal power plants. This is achieved by passing the exhaust steam into a condenser (called a surface condenser), which condenses the exhaust steam from the low-pressure stages of the main turbine (decreases the temperature and pressure of exhausted steam).
What is GSC in turbine?
GSC (Gland steam condenser) is simply an efficiency improver in thermal power plants. The working of GSC is quite simple as like condenser. It has shell inside which some tubes are mounted.
What is leak off steam in turbine?
Leak-off steam from the seals of the main stop and control valves is also discharged into the TGSS header. The steam seal leak-off valve is a pneumatically actuated pressure control valve, which fails to the position designated by the turbine supplier.
How does steam drive a turbine?
In simple terms, a steam turbine works by using a heat source (gas, coal, nuclear, solar) to heat water to extremely high temperatures until it is converted into steam. The potential energy of the steam is thus turned into kinetic energy in the rotating turbine’s blades.
How do you start a steam turbine?
Start the vacuum pump and bring up the vacuum in the condenser. Open condensate pump valves and switch on the pump. Check whether the condensate vacuum, gland steam pressure, steam inlet pressure, and lube oil pressure are normal. Start turbo generator from the local station and close the drain in the steam line.
What is condensing type turbine?
The condensing turbines take high pressure steam, expand it in turbine nozzles and blades, and exhaust it to a condenser at lower than atmospheric pressure. It is principally used when power must be generated with minimum steam consumption. These turbines are of bleed cum condensing type.
How does a steam turbine spin?
As the name implies, a steam turbine is powered by steam. As hot, gaseous steam flows past the turbine’ spinning blades, steam expands and cools, giving off most of the energy it contains. This steam spins the blades continuously. The blades thus convert most of the steam’s potential energy into kinetic energy.

What is the difference between steam engine and steam turbine?
While, steam engine and steam turbine use the large latent heat of vaporization of steam for the power, the main difference is the maximum revolution per minute of the power cycles that both could provide. In turbines, there are vanes designs with steels to give a rotary movement with the steam flow.
