TURBINES AND ITS TYPES

3. A machine for producing continuous power in which a
wheel or rotator typically fitted with vanes. Is made to
revolve by a fast moving flow of water, steam, gas,
air, or other fluid and converts it into useful work.
OR
Turbines convert the kinetic energy of a moving fluid
or gas into rotational energy that can be used to drive
a dynamo and generate electricity usually the source
of kinetic energy is steam, although it can sometimes
be water.

6. The working principle is very much simple.
1. When the fluid strikes the blades of the
turbine, the blades are displaced, which
produce rotational energy.
2. When the turbine shaft is directly coupled to
an electric generator mechanical energy is
converted into electrical energy.
3. This electrical power is known as
hydroelectric power.

8. 1. Wind turbine
2. Steam turbine
3. Gas turbine
4. Water turbine
Although the same principles apply to all
turbine their specific designs differ sufficiently to
merit separate descriptions.

9. A wind turbine is a device that converts kinetic
energy from the wind into electrical power.
Conventional horizontal axis turbines can be
divided into three components:
1. The rotator component
2. The generator component
3. The structural support component

10. Wind Turbine

11. - A steam turbine is a device that extracts
thermal energy from pressurized steam and
uses into do mechanical work on a rotating
output shafts.
- Steam turbines are used for the generation
of electricity in thermal power plants, such as
plants using coal fuels oil or nuclear fuel.

13. Open steam turbine

14. A gas turbine is also called a combustion
turbine, is a type of internal combustion
engine.
- Fresh atmospheric air flows through a
compressor that brings it to higher pressure.
- Energy is then added by spraying fuel into
the air and igniting it so the combustion
generates a high-temperature flow.
- These are used to power aircrafts, trains,
ships, electrical generators or even tanks.

15. GASTURBINE

16. Water turbine is divided in following turbines:
- Impulse turbine
- Reaction turbine

17. - In an impulse turbine, fast moving fluid is fired
through a narrow nozzle at the turbines blades to
make them spin around.
- The blades of an impulse turbines are usually
bucket shaped so they catch the fluid and direct it
off at an angle.
- In an impulse turbine, the fluid is forced to hit the
turbine at high speed.

18. - In a reaction turbine, forces driving the rotor
are achieved by the reaction of an
accelerating water flow in the runner while
the pressure drops. The reaction principle can
be observed in a rotary lawn sprinkler where
the emerging jet drives the rotor in the
opposite direction.

19. Continue…
- In reaction turbine torque developed by
reacting to the fluid’s pressure. The
pressure of the fluid changes as it passes
through the turbine rotor blades.
