1.1.Electrical energy is energy made available by the flow of electric charge through a conductor. Electrical power is the backbone of modern industrial society, and is expected to remain so for the foreseeable future. Electricity's extraordinary versatility as a source of energy means it can be put to an almost limitless set of applications which include transport, heating, lighting, communications, and computation.
Electricity in bulk quantities is produced in power plants, which can be of the following types:
(a)Thermal (b) nuclear (c) hydraulic (d) gas turbine and (e) geothermal.
Power plants work with steam as the working fluid and have many similarities in their cycle and structure. Gas turbine plants are often used as peaking units. They run for short periods in a day to meet the peak load demand.
1.2. THERMAL POWER PLANT IN TAMIL NADU:-
Power Station | Location | District | State | Installed Capacity (MW) |

Ennore TPS | Ennore | Chennai | Tamilnadu | 450 |
Mettur TPS | Metturdam | Salem | Tamilnadu | 840 |
Tuticorin TPS | Tuticorin | Tuticorin | Tamilnadu | 1050 |
Neyveli TPS 1 | Neyveli | Cuddalore | Tamilnadu | 1020 |
Neyveli TPS 2 | Neyveli | Cuddalore | Tamilnadu | 1470 |
Neyveli Zero Unit | Neyveli | Cuddalore | Tamilnadu | 250 |
1.3. GENERAL LAYOUT OF THE PLANT:
There are four main circuits in any thermal power plant and these are
* Air & ash Circuit
* Feed water & steam circuit
* Cooling water circuit
* Coal handling circuit
1.3.1. COAL: Coal is the principal energy source, particularly in India because of its large deposits and availability. Coal originates from huge geological upheavals buried these bogs under layers of slit. Subterranean heat, soil pressure and movement of earth crust distilled off some of bog’s... [continues]
