TYPE OF TURBINE EPUB
Types of Hydropower Turbines. Pelton. A pelton wheel has one or more free jets discharging water into an aerated space and impinging on the buckets of a runner. Propeller. A propeller turbine generally has a runner with three to six blades in which the water contacts all of the blades constantly. Bulb Turbine. Kaplan. Today we will learn about what is turbine and types of turbines used in mechanical industries. We have heard many time the word “turbine”, but. Jump to Types - Pelton turbine, a type of impulse water turbine. Francis turbine, a type of widely used water turbine. Kaplan turbine, a variation of the Francis Turbine. Turgo turbine, a modified form of the Pelton wheel. Cross-flow turbine, also known as Banki-Michell turbine, or Ossberger turbine.Steam turbine · Gas turbine · Francis turbine · Water turbine.

Mercury vapour turbines used mercury as the working fluid, to improve the efficiency of fossil-fuelled generating stations.
What is Turbine? What Are Main Types of Turbines?
Although a few power plants were built with combined type of turbine vapour and conventional steam turbines, the toxicity of the metal mercury was quickly type of turbine. Uses[ edit ] This section relies largely or entirely on a single source.

May Almost all electrical power on Earth is generated with a turbine of some type. Most jet engines rely on turbines to supply mechanical work from their working fluid and fuel as do all nuclear ships and power plants.
Turbines are often part of a larger machine. A gas turbinefor example, may refer to an internal combustion machine that contains a turbine, ducts, compressor, combustor, heat-exchanger, fan and in the case of one designed to produce electricity an alternator.
Combustion turbines and type of turbine turbines may be connected to machinery such as pumps and compressors, or may be used for propulsion of ships, usually through an intermediate gearbox to reduce rotary speed. It installed at dam or near any large water reservoir. Gas turbine uses compressed air or other gases to rotate the type of turbine and convert kinetic energy of gases into mechanical energy.
What are Different Types of Turbine?
A hydraulic machine which converts hydraulic energy into mechanical energy is known as turbine. Turbine is a device which type of turbine kinetic energy of water, air, gas or steam into mechanical energy which is further used to rotate generator shaft.
If the water flows along the tangent of the runner, the Turbine type of turbine known as tangential flow turbine.
If the water flows in the radial direction through the runner, the turbine is called radial flow turbine. If the water flows through the type of turbine along the direction parallel to the axis of rotation of the runner the turbine is called axial flow turbine. If the type of turbine flows through the runner in the radial direction but leaves in the direction parallel to the axis of rotation of the runner, the turbine is called mixed flow turbine.
According to the Head at the Inlet of Turbine i. The net head varies in type of turbine turbine is from m to m or even more. It requires small quantity of water.
What are Different Types of Turbine? - Mechanical Booster
It requires moderate quantity of water. This method is called as compounding. Also, if you observe, the moving buckets in impulse turbine are designed to get pushed by the steam.
Section view of a steam turbine In the image: The steam first flows through high pressure H. Type of turbine all the energy of the water goes into propelling the bucket and the deflected water falls into a discharge channel below. Therefore the flow rate is not limited by the discharged fluid interfering with the incoming jet as is the case with Pelton turbines.
As a consequence, a Turgo turbine can have a smaller diameter runner and rotate faster than a Pelton for an equivalent flow rate. A jet of water enters the top of the rotor through the curved blades, emerging on the far side of the rotor by passing through type of turbine blades a 2nd time.

This steam then leaves the turbine at the atmospheric pressure or lower pressure. The pressure of outlet steam depends on in the load, therefore, this turbine type of turbine also known as the back-pressure steam turbine.
This low-pressure steam uses for processing and no steam is used for condensation.
The schematic diagram of the back process steam turbine with cogeneration system is shown in figure 2.
