Rotor. It is the mobile element of the system. The energy released by the steam in the turbine is converted into mechanical energy in this element. Since the turbine is divided into a certain number of steps, the rotor is made up of a series of blade crowns, one for each step of the turbine.

What is a turbine and its parts?

The turbine is made up of three main parts: The body of the rotor, which contains the rotating rims of blades. The casing, containing the fixed nozzle crowns. Praise.

What is a turbine and how does it work?

turbine meaning

Its operation is based on the paddles located on the circumference of the wheel. The liquid that enters the turbine generates tangential force providing the movement of the wheel, causing its rotation. The axis is in charge of transmitting this mechanical energy to another machine or device.

What is a turbine casing?

Casing: The casing protects and insulates the interior of the turbine and can be divided into 3 longitudinal sections: Compressor casing: It is made up of a single layer to support the fixed blades and to conduct cooling air to subsequent stages of the gas turbine .

What are the main parts of a steam turbine?

The essential parts of a turbine are a shaft, rotor with blades or blades, casing, bearings and seals; additionally it has other parts, auxiliaries or accessories such as diagrams, discs, oil system, lubricant, regulation systems, foundations, instrumentation (control, protection, etc.)

What are the main parts of gas turbines and the auxiliary systems necessary for their operation?

The main elements of the gas turbine are five: the air intake, the compressor, the combustion chamber, the expansion turbine and the rotor.

How do reaction turbines work?

The reaction turbines are activated through the pressure that the liquid exerts on the blades. This pressure decreases from the leading edge to the blade exit. In this type of turbine, the rotor takes advantage of the pressure with which the water leaves the blades.

How does a steam turbine work?

The operation is very simple: steam is introduced at a certain temperature and pressure and this steam turns some blades attached to a rotor shaft; At the turbine outlet, the steam introduced has a lower pressure and temperature.

What are the types of turbines?

There are three main types of turbine, depending on the flow of water and the difference in height, they are the Francis turbine, the Pelton turbine and the Kaplan turbine. The Francis turbine was developed in 1848 by the French engineer James B.

What are the characteristics of a steam turbine?

In general, a steam turbine is a rotary heat engine that converts the thermal energy contained in steam into mechanical or electrical energy. In its simplest form, a steam turbine consists of a boiler (steam generator), turbine, condenser, feed pump.

How do ship turbines work?

A simple cycle gas turbine includes a compressor that draws air at atmospheric pressure and compresses it to be injected into the combustion chamber. The fuel, in gaseous or nebulized form, is also injected into said chamber, where combustion takes place.

How does the Kaplan turbine work?

The Kaplan turbine is a hydraulic turbine that uses small gradients, up to a few tens of meters, but with large flows, from 200/300 m³/s. Constructively, this type of hydraulic turbine is a propeller, where the blades can be oriented, since the water flow varies.

How do turbines rotate?

The basic element of the turbine is the wheel or rotor, which has blades, propellers, blades or hubs placed around its circumference, in such a way that the moving fluid produces a tangential force that drives the wheel and makes it rotate.

How to generate energy from water?

A coal-fired power plant uses heat to heat water and produce steam that drives the turbine blades, in contrast to a hydroelectric plant, which uses the precipitation of falling water to drive the turbine. The same results are obtained with both procedures.

How does the combustion chamber of a turbine work?

Heat is introduced into gas turbines through the combustion chamber. This chamber receives the compressed air from the compressor and sends it at a high temperature to the expander turbine, ideally without pressure loss.

How does a gas turbine work?

Air enters through the turbine intake. The compressor increases the pressure of the air before it enters the combustion chamber. This compressed air is then mixed with fuel and ignited, creating a hot gas that expands.

How are Kaplan turbines classified?

Turbines are classified into hydraulic or water turbines, steam turbines and combustion turbines.

What are the components of the Kaplan turbine?

Kaplan turbines are the most efficient water turbines, as they work just like a ship’s engine propeller.

The items they have are:

    Shaft.Suction turbo.Spiral chamber. Distributor.Turbine guide bearing.Turbine shaft sealing kit.Thrust bearing.

How does the Brayton cycle work?

It consists of giving pressure to the air and then heating it by burning fuel. Subsequently, this high-temperature gas is passed through a turbine where its energy is extracted; A portion of that energy is used to drive the compressor, and the remaining energy is used to turn an electric generator.

How are steam turbines classified?

Steam turbines can be classified according to the way in which the energy contained in the steam flow is used (reaction or action), according to the number of stages (multi-stage or single-stage), according to the direction of the steam flow (axial or radial), whether or not there is steam extraction before arriving …

How is a steam turbine built?

Creating the steam turbine is really simple. The first thing we are going to do is fill the can three-quarters full with water and seal it at the top with some kind of sealant to prevent steam from escaping. We must leave a space to place a small plastic tube where the steam will come out.

What types of steam turbine are there?

We have two general types of steam turbines, action and action-reaction. Action turbines: The steam is distributed to the entire section by means of nozzles. At the outlet of the nozzles, the energy of the steam is transformed into kinetic energy that moves the blades.

How are gas turbines classified?

They can be classified according to the origin of their development, by the design of their combustion chamber and by their number of axles. Aeroderivative gas turbine: They come from the design of turbines for aeronautical purposes, but adapted to the production of electrical energy in industrial plants or as micro turbines.
