Thermal Power Plant презентация

Working principles:
Thermal power station's works like this:
Heat released by burning fuel which produces working fluid steam from water. Generated steam runs the turbine coupled to a generator which produces electrical energy in Thermal Power Plants.

1. Boiler:
Here Coal is burning which means that the heat is producing that heats used to heat the water and the water changes its property and then it sends to superheater, here it becomes steam with high heated.
2. Condenser:
The condenser presents here to cool the working fluid or we can say to remove the heat from the water.
3. Economizer:
When water pressure gets increased there some amount of heat generates and that heat sends from the economizer to the boiler.
4. Turbine:
The main function of the turbine is that when steam strikes to the turbine the blade rotates and it converts the Heat energy into mechanical energy.
5. Generator
In Thermal Power Plant station generator uses to generate electricity to rotate turbine.
The generator, typically about 30 feet long and 12 feet in diameter, contains a stationary stator and a spinning rotor, each containing miles of heavy copper conductor. There is generally no permanent magnet, thus preventing black starts. In operation it generates up to 21,000 amperes at 24,000 volts as it spins at either 3,000 or 3,600 rpm, synchronized to the power grid.
6. Cooling tower
A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a coolant stream, usually a water stream to a lower temperature.

Advantages:
Disadvantages:
Thermal power station has less initial cost as compared to hydro-electric generating station.
It requires less space as compared to the hydro-electric power station.
The fuel cost is less as compared to gas.
Hung amount of power can be generated by TPS.
The cost of generation is less as compared to diesel power station.
The running cost of thermal power station is more as compared to hydro power station.
It pollutes the atmosphere due to production of large amount of smoke and fumes.
Maintenance cost is more.
Skilled persons are required for erecting and maintaining the power station.
Land requirement is more for storage of coal and ash.
