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 …
What type of pump is mostly to be driven by steam turbines?
Applications of steam turbines include large power station generators, ship propulsion, compressors and pumps. This 3D model shows a centrifugal pump driven by a steam turbine.
What are the accessories of steam turbine?
Steam Turbine parts
- Stator / Diaphragm.
How does a steam driven pump work?
The steam enters at one side of the steam cylinder through the slide valve and pushes the piston towards the opposite side. As the piston reaches the end of the stroke, the slide valve reverses the steam flow, which reverses the piston movement.
What are the 3 basic parts of a turbine?
A wind turbine consists of five major parts and many minor parts. The main components are the foundation, the tower, the rotor and hub (including three blades), the nacelle, and the generator.
What are the parts of turbine?
15.1 includes 14 major components common to many modern wind turbines: three blades, three pitch bearings, a hub, main bearing, main shaft, gearbox, generator, main frame, yaw bearing, and tower.
What type of pump is a turbine pump?
Turbine pumps are special types of centrifugal pumps which use turbine-like impellers with radially oriented teeth to move fluid. They are also referred to as vortex, periphery, or regenerative pumps.
Is turbine pump a centrifugal pump?
Turbine pumps are centrifugal in nature but have some characteristics of positive displacement. While that sounds oxymoronic, for different functions, they behave or operate differently. First, the way they impart energy to the liquid is kinetic (and hence centrifugal) in nature.
What is Casing in steam turbine?
Steam turbines consist essentially of a casing to which stationary blades are fixed on the inside and a rotor carrying moving blades on the periphery. The rotor is fitted inside the casing with the rows of moving blades penetrating between the rows of fixed blades.
What is turbine driven pump?
Turbine pumps are dynamic pumps, meaning they utilize fluid momentum and velocity to generate pump pressure. Specifically, they are centrifugal pumps, which generate this velocity by using an impeller to apply centrifugal force to the moving liquid.
What is turbine drive?
Steam turbine drives are equipped with throttling valves or nozzle governors to modulate steam flow and achieve variable speed operation. The steam turbine drive is thus capable of serving the same function as an induction motor coupled to an inverter or adjustable speed drive.
What are parts of turbine?
- 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.
Why steam turbines are preferred over steam engines?
The superheated steam entering the turbine loses its pressure (enthalpy) moving through the blades of the rotors, and the rotors move the shaft to which they are connected. Steam turbines deliver power at a smooth, constant rate, and the thermal efficiency of a steam turbine is higher than that of a reciprocating engine.
What are the stages of a steam turbine?
Based on Steam Movement. On the basis of steam speed,these are classified into different types,which include the following.
Why does water turbine have higher efficiency then steam turbine?
Reheating increases turbine efficiency in the same way as for a steam turbine by optimising power turbine and gas flow conditions. Furthermore, it can allow the turbine to achieve higher efficiency with a lower turbine inlet temperature, making less demand on material performance.
Is there a better alternative to the steam turbine?
• Gas turbines can deliver either torque or thrust as the work output, while steam turbines almost all the time delivers torque as the work output. • The efficiency of the gas turbines is much higher than the steam turbine due to higher operating temperatures of the gas turbines.
