In this article we are going to discus about the turbine working and application. We will discuss about the impulse and reaction turbine. We will also discuss about the impulse and reaction turbine. In this article we know about the advantage and disadvantage of impulse and reaction turbine.
Turbine Working and Application
Turbine is a mechanical machine which converts kinetic energy into electrical energy.
It takes energy from moving liquid or gas and starts rotation. When turbine is rotate, kinetic energy is generated and by using of kinetic energy we can generate the electrical energy. For generation of electricity a alternator is connected with a shaft to the turbine. So when turbine starts rotation after getting pressure of moving steam or liquid, the alternator is also rotates with same speed and electricity is produced.
Turbine Construction and working
Turbine has its three two main parts.
1) curved blades- it catch the moving fluid or gas
2) shaft- rotate the blades
Turbine working Method
The turbine works in two different methods
1) Impulse turbine
2) Reaction turbine
Impulse turbine working
Impulse turbine is simple turbine. In impulse turbine a high speed fluid is comes through a narrow nozzle to the turbine blades for rotation of turbine. The blade of impulse turbine is bucket shaped so that it gives a gives a perfect angle and rotates the turbine. So this is a simple construction turbine and easy to understand. This is a high efficient turbine also. Water turbine is a example of impulse turbine, this is used in hydro power plants.
Advantage of Impulse Turbine
- It is in easy to construct because it has simple design.
- It is a cheap turbine.
- It has less maintenance.
- It can be use in reverse direction.
Reaction turbine working
Reaction turbine reacts when it has pressure of fluid, and developed torque.
The working of reaction turbine is based on Newton’s third law i.e. action and reaction is equal and opposite. In reaction turbine a nozzle is attached to the rotating blades. When pressured fluid leaves the nozzle it produce reaction force on the pipe and rotor is starts rotation in opposite direction to that fluid. When fluid is passes through the blades its pressure got low.
Wind turbine, Steam turbine are main example of reaction turbines.
Advantages of reaction turbine
1) It is a highly efficient as compared to impulse turbine.
2) Output power is more.
Some examples of turbine with their working and application
1) Steam turbine Working and application
This is a reaction turbine. Steam turbine is used in thermal power plants. This is used to convert thermal energy into mechanical and electrical energy. In thermal power plant water is superheated with combustion of coal. For combustion boiler is used. When water is superheated it converts into steam.
This steam is comes in turbine blades jet. And turbine starts rotation. When turbine is rotates a mechanical energy is generated on its shaft. This mechanical energy can be used for rotating of motor, pump, alternator Etc.
2) Water turbine working and application
water turbine is also known as hydro turbine. Water turbine is a impulse turbine.The water is fallen down on its blades from a high head. This water has much kinetic energy. When water heats the blades the turbine starts rotation, and mechanical energy is produce. By using a alternator this mechanical energy can be converted into electrical energy. It has a simple design.
3) Wind turbine working and application
Wind turbine is of two types vertical axis and horizontal axis. This converts kinetic energy of wind into electricity. It installed at a height cause to get wind pressure. When wind pressure comes to its blades the rotor starts rotation and by connected generator starts generation of electricity. Wind turbine speed is very slow as compared to above turbines.
Hence these are turbine working and application if you will find any incorrect in above article you must comment box.
