A simple turbine.
Air is drawn into the engine continuously and compressed by a series of rotating blades. Fuel is sprayed into the combustion chamber and burnt increasing the gas temperature to around 1200C.
The hot high pressure gas expands through a second set of blades mounted on the same shaft as the compressor blades. The energy of the gas is partially expended powering the compressor, but has a residual energy which is either expended as a hot jet (resulting in thrust) or which drives a further independent set of blades to power a propeller or other device.

This type of turbine makes use of the reaction force produced as the steam accelerates through the nozzles formed by the rotor. Steam is directed onto the rotor by the fixed vanes of the stator. It leaves the stator as a jet that fills the entire circumference of the rotor. The steam then changes direction and increases its speed relative to the speed of the blades. A pressure drop occurs across both the stator and the rotor, with steam accelerating through the stator and decelerating through the rotor, with no net change in steam velocity across the stage but with a decrease in both pressure and temperature, reflecting the work performed in the driving of the rotor. les.

∙ 15y agoTurbines used for power production can be powered by steam, gas, water, or wind. Steam turbines are used in power plants fuelled by fossil fuels or nuclear reactors. They operate in the Rankine cycle, in which high pressure steam is admitted and expanded in successive stages until its temperature and pressure have fallen to low levels (in fact the last stage of the turbine operates in a partial vacuum), after which the steam is condensed by cooling water and returned to the steam raising boilers. The turbine shaft is coupled to a generator which exports the electric power.
Gas turbines are powered by burned natural gas in a straight through arrangement but often the exhaust gas is used for secondary heating for a district or large industrial plant. These are called CHP schemes (Central Heating and Power)
Water turbines are used in hydro schemes where water falls from a high level reservoir or lake before entering the turbine.
Wind turbines are used coupled to a three bladed wind airscrew, mounted on a tall mast.

∙ 14y agoBasically, a gas turbine is powered by gas under pressure, The gas is pressurized by burning some type of fuel such as kerosene, jet fuel, or propane. That heat causes air expansion, and the subsequent inflow of air makes the turbine spin.
A gas turbine consists of three main parts; a combustion chamber, a turbine and a compressor. Air and fuel are mixed in the combustion chamber where it is ignited and increases in speed and power. This power is directed over the turbine blades which spin the turbine and power the compressor.
It's a pretty simple process: heated fuel causes pressure and air expansion. The expanded air causes a turbine to spin. That is how gas turbines like jet engines work.

What are the capacity of Steam Turbines?
The capacity of each steam turbines has more than 530 GW in over 6000 installed units. The steam turbines provide high reliability and sustained high efficiency.
What is the necessary of compounding in turbines?
compounding of turbines is necessary to make the turbines practically controllable.If compounding is not done the size of the turbine will be huge.Hence by pressure &velocity compounding the turbine becomes small in size &its velocity is also becomes controllable.
What is the function of draught tube?
A draft tube is used to transform water into energy. It is found in the piping system of jets, dams or anywhere turbines help with difficult mechanical work.
What is normal Excess air in gas turbines?
10 to 20 %
Whats the difference between windmills and wind turbines?
Windmills are much shorter than wind turbines, and usually have many blades. The blades catch more wind causing the windmill to be able to do more physical work. The propeller blades are connected to an axle with gears. The gears are connected to a vertical shaft that runs down the length of the tower and is connected to other mechanical equipment. Windmills do work such as pump water or grind grain, which is why they are a common site on farms where they are used in crop production. They are not built to produce electricity.HOPE THIS HELPED!!!!!!!
How does a tidal stream generator work?
Tidal Turbines work when the tide goes in and out. The force from the movement of the water spins the turbines.
What needs wind to work?
wind turbines
How do wind farms work?
wind farms are built and turbines are put up. As the wind blows it turns the turbines generating electricity.
How much fossil fuels can wind turbines use in one day?
it takes about 10 turbines for 1 fossil fuel to work.
How long will hydroelectricity work?
So long as there is enough water to run the turbines.
What are some of the disadvantages of wind turbines?
They dont work if its too windy and have to be shut down
How does it work for hydroelectric equipments?
Hydroelectric power works by running water over the turbines of a power plant inside of a dam. The power of the rushing water turns the turbines and produces electricity.
How does the systems generally work?
Take for example, a dam. Water flows through the gates (when opened) of the dam and turn turbines. Inside these turbines are coils of copper usually that generate electricity.
Are wind turbines more cost effective than solar panels?
It depends on where you live. Solar panels work well in desert areas. While wind turbines work best near large lakes, oceans, or mountains. Wind turbines need to be very high up and solar panels need to face the sun as it moves across the sky.

What are some of the different designs of wind turbines?
country side wind turbines and modern turbines
Is it possible to attach small wind turbines over trains?
If you're talking about sticking turbines onto the train: It's possible, but pointless. The turbines would spin due to wind speed generated by the movement of the train, so all the power that is going into the turbines has come from the train in the beginning. Basically you're using the motor of the train to spin the generator of the turbines. The train has to work harder, and the energy you get from the turbines will be less than the extra energy that's being spent by the train. If you're talking about sticking wind turbines by the track, to spin by the pressure wave: That's also possible, but almost as pointless. Turbines by the track would resist air flow, and when the train is travelling it will push a cushion of air in front of it. Something getting into the way of this air cushion, (like turbines) would basically make the air in front of the train denser, and harder to push through. On top of that, there aren't many places where trains go by all the time, so the turbines wouldn't have much to work with.
