What are the capacity of Steam Turbines?
The capacity of each steam turbines has more than 530 GW in over 6000 installed units. The steam turbines provide high reliability and sustained high efficiency.
What is different betweeb single stage and multi stage steam turbine?
In a single stage steam turbine the steam is run through a nozzle to give it maximum velocity, thus the blades move at very high speeds, impractical for some applications, and only some of the energy is used, about 85-90%. In multi-stage or compound turbines the steam goes through a nozzle to increase its velocity, then after going through a set of blades, it is run through another nozzle to bring the steam back up to the correct velocity. After multiple stages there is no longer enough pressure left to up the velocity of the steam. This method increases the efficiency of the turbine and also decreases wear on the components caused by the high speed of a single stage.
Why is convergent-divergent nozzle generally used in steam turbines?
A convergent-divergent nozzle is generally used in steam turbines. This is because it drives generators in producing electricity with the use of turbine rotors with curved axes.
What happens to the steam after it has passed through the turbines?
It is cooled to liquid and fed back into the boiler for reheating.
Where the guide vanes are fixed in steam turbines?
In steam turbines, guide vanes are typically fixed in the turbine's stationary casing or casing sections, located before the rotor blades. Their primary function is to direct the flow of steam towards the rotor blades at the optimal angle, ensuring efficient energy transfer. By maintaining a fixed position, they help stabilize the steam flow and improve the overall performance of the turbine.

What is the methods of compounding of steam turbines?
no
What type of combustion engine would you classify steam turbines used in power plants?
Steam turbines are external combustion engines.
Why is excessive moisture in steam undesirable in steam turbines?
moisture present in steam due to quality of steam.

Why vacuum is created in steam turbines?
Vacuum is created in steam turbines to increase the efficiency of the turbine by lowering the pressure at the exhaust end, which allows the steam to expand and produce more work. This helps to generate more power from the same amount of steam.
How can steam be turned into usable energy?
The steam can be used to turn a generator's turbines and make electricity.
