What is steam turbine Slideshare?
A steam turbine is a prime mover in which the potential energy of the steam is transformed into kinetic energy and later in its turn is transformed into the mechanical energy of rotation of the turbine shaft. Read more. Engineering.
What are the parts of the turbine?
A wind turbine consists of five major and many auxiliary parts. The major parts are the tower, rotor, nacelle, generator, and foundation or base. Without all of these, a wind turbine cannot function. The foundation is under the ground for the onshore turbines; it cannot be seen because it is covered by soil.
What are the 4 main parts of a turbine?
The makeup of a wind turbine can range depending on the maximum output, but each usually consist of four main wind turbine parts:
- Generator (Nacelle)
- Rotor blades.
- Tower.
- Foundation.
What is nozzle in steam turbine?
The steam nozzle is a passage of varying cross-section by means of which a part of the enthalpy of steam is converted into kinetic energy as the steam expands from a higher pressure to a lower pressure. Therefore, a nozzle is a device designed to increase the velocity of steam.
What are turbine blades called?
A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor.
How many types of turbine are there?
1 Turbine. A turbine is a work producing device. Production of power is achieved by expanding a fluid. Mainly, there are two different types of turbines, steam and gas turbines.
What is turbine rotor?
The rotor connects to the generator, either directly (if it’s a direct drive turbine) or through a shaft and a series of gears (a gearbox) that speed up the rotation and allow for a physically smaller generator. This translation of aerodynamic force to rotation of a generator creates electricity.
What are turbine vanes?
Guide Vanes are fixed grooves found in turbines that help direct water, gas, or air around bends at maximum efficiency. As Impellers increase or decrease the flow of a substance through a system, Guide Vanes ensure that the substance is passed evenly and as smoothly as possible.
What are the basic parts of steam turbine?
In this presentation study on the basic parts of the steam turbine as following turbine casting, turbine rotors, turbine blades, shrouds, turbine bearing device, turbine seals, turbine couplings, governor and lubrication system. 1. DEPARTMENT OF MECHANICAL ENGINEERING Presentation on BASIC PARTS OF STEAM TURBINE PES1201702403 2.
How is power obtained in a steam turbine power plant?
-The Power in a steam turbine is obtained by the rate of change in momentum of a high velocity jet of steam impinging on a curved blade which is free to rotate. -The basic cycle for the steam turbine power plant is the Rankine cycle.
What is a stage in a steam turbine?
Each set of one row of nozzles and one row of moving blades is referred to as a stage This involves splitting up of the whole pressure drop from the steam chest pressure to the condenser pressure into a series of smaller pressure drops across several stages of impulse turbine. The nozzles are fitted into a diaphragm locked in the casing.
How does a steam turbine condenser vacuum system work?
The cooling water condenses the steam turbine exhaust steam in the condenser creating the condenser vacuum. As a small amount of air leaks into the system when it is below atmospheric pressure, a relatively small compressor (Vacuum pump) or Air Ejector System removes non-condensable gases from the condenser. 38.
