What are the two main types of steam turbines?
Two types of steam turbines must be considered, condensing and noncondensing.
What is the principle of steam 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. As that steam flows past a turbine’s spinning blades, the steam expands and cools.
What is steam turbine simple definition?
A steam turbine is a device that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. A steam turbine connected to an electric generator is called a turbo generator.
What are the parts of steam turbine?
The main parts of a steam turbine are (1) the rotor that carries the blading to convert the thermal energy of the steam into the rotary motion of the shaft, (2) the casing, inside of which the rotor turns, that serves as a pressure vessel for containing the steam (it also accommodates fixed nozzle passages or stator …
Why compounding of steam turbine is done?
Compounding of steam turbine is used to reduce the rotor speed. It is the process by which rotor speed come to its desired value. A multiple system of rotors are connected in series keyed to a common shaft and the steam pressure or velocity is absorbed in stages as it flows over the blades.
What is steam chest in turbine?
Steam is admitted to a turbine from the superheater outlets, via the hieh pressure steam mains, to the emergency stop valves and the associated governing valves which are housed in steam chests. These steam chests, one on each side, contain one large emergency stop valve and one governor valve each.
How can you make a steam turbine more efficient?
Three new methods of increasing efficiency of turbine power plants are described: reheating of steam turbine, regenerative feed heating of steam turbine, and by binary vapour cycle of steam turbine.
Which of the following is not a type of steam turbine?
1. Which of the following is not a type of steam turbine? Explanation: Pelton wheel turbine is a water turbine. Impulse and reaction turbines are the steam turbines characterized by the action of steam on moving blades.
What cycle does steam power plant work?
Rankine cycle
What are the 3 things that impact power production of wind turbines?
Several different factors influence the potential wind resource in an area. The three main factors that influence power output are: wind speed, air density, and blade radius.
