What else can I help you with?
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 is the control stage in steam turbines?
The control stages are the stages at which steam is admitted to or extracted from the turbine. These "control" the output of the turbine.
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.
Why is superheated steam preferred in a turbine?
among other things, to improve thermal efficiency and minimize ( transmission losses) as the steam cycles through the turbines, these are often l00% Heavy Duty cycles as in Powerhouse service and Nuclear submarines. turbines use superheated steam in order to avoid condensation inside, and, as a result, erosion of the blades. Superheated steam also contains more potential energy (expressed as an enthalpy).
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.
Do they still make steam engines?
Yes, turbines used today are radial steam engines.
How did the navy use nuclear power?
The Navy uses Nuclear Power to create steam. Steam is then used to power steam turbines, which in turn power the ship's screws and generators. The US Navy has steam plants, gas turbines, diesel and nuclear powered vessels.
