What are the components of a steam turbine?
What are the components of a 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 …
What are the 3 basic parts of a turbine?
Turbine Components
- Rotor Blades – The rotor blades of a wind turbine operate under the same principle as aircraft wings. One side of the blade is curved while the other is flat.
- Nacelle – The nacelle contains a set of gears and a generator.
- Tower – The blades and nacelle are mounted on top of a tower.
What are the two types of steam turbine?
Two types of steam turbines must be considered, condensing and noncondensing.
What is working 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. The potential energy of the steam is thus turned into kinetic energy in the rotating turbine’s blades.
What are the types of steam turbine?
Steam Turbines. Three basic types of steam turbine are used to generate power as a by-product of process or exhaust steamml: condensing, pass-out condensing, and back-pressure.
What are the main parts of a turbine?
The turbine components to be installed are the tower, nacelle, hub and blades.
How steam turbine is manufactured?
A steam turbine rotor having a combination of at least one of a high pressure rotor, an intermediate pressure rotor and a low pressure rotor, which are each formed from a metal material of different chemical composition and welded together by means of welding.
What material is used in turbine casing?
A material used for the casing is 1Cr-1Mo-1/4V low carbon alloy cast steel or 11Cr-1Mo-V-Nb-N cast steel. From the standpoint of exhaustion of fossil fuel such as petroleum, coal and so on and energy saving, it is required to improve the efficiency of a thermal power plant.
What are the parts and functions of steam turbine?
Parts and functions of steam turbine: 1 Rotor 2 Stem chest 3 Casing 4 Over speed trip system 5 Governor system
What is a reversing blade on a steam turbine?
The reversing blades reverse the steam flow as it exits the first row of blades and directs the steam into the second row of blades of the Curtis stage. The reversing blade assembly is positioned axially by spacers.
What is governor system in a steam turbine?
Governor system: Governor systems are speed-sensitive control systems that are integral with the steam turbine. The turbine speed is controlled by varying the steam flow through the turbine by positioning the governor valve. Consists of spring-opposed rotating weights, a steam valve, and an interconnecting linkage or servo motor system.
What is the function of the steamer cylinder parts?
This part is fitted on the crank end cover of the cylinder and their function is to prevent the leakage of steam past the piston rod. It is the cast iron cylindrical disc moving to and fro in the cylinder under the action of the steam pressure. This part converts heat energy of steam into mechanical work.
