4. HOW TO WORK THERMAL POWAR PLANT

5. What is mean by thermal power plant ?
• A thermal power station is a power station in which heat energy is converted to electric power. In most
of the places in the world the turbine is steam-driven. Water is heated, turns into steam and spins a steam
turbine which drives an electrical generator. More than 65% of India's electricity generation capacity comes
from thermal power plants, with about 85% of the country's thermal power generation being coal-based.
The 10 biggest thermal power stations operating in India are all coal-fired, with seven of them owned and
operated by state-run National Thermal Power Corporation (NTPC). Power-technology.com profiles India's
10 biggest thermal power plants by installed capacity.

6. Steam turbine generator:- (Turbo generator)
0
• Rotor of a modern steam turbine, used in a power station
• The turbine generator consists of a series of steam turbines interconnected to each other and a
generator on a common shaft. There is usually a high-pressure turbine at one end, followed by
an intermediate-pressure turbine, and finally one, two, or three low-pressure turbines, and the
generator

7. Boiler make-up water treatment plant and storage
• Since there is continuous withdrawal of steam and continuous return of condensate to the
boiler, losses due to blow down and leakages have to be made up to maintain a desired water
level in the boiler steam drum. For this, continuous make-up water is added to the boiler water
system.

8. Fuel preparation system
• Conveyor system for moving coal (visible at far left) into a power station.
• In coal-fired power stations, the raw feed coal from the coal storage area is first crushed into
small pieces and then conveyed to the coal feed hoppers at the boilers. The coal is
next pulverized into a very fine powder. The pulverizes may be ball mills, rotating
drum grinders, or other types of grinders.
• Some power stations burn fuel oil rather than coal.

9. •Oil system :-
An auxiliary oil system pump is used to supply oil at the start-up of the steam
turbine generator. It supplies the hydraulic oil system required for steam turbine's main inlet steam
stop valve, the governing control valves, the bearing and seal oil systems, the relevant hydraulic
relays and other mechanisms.
• Barring gear :-
Barring gear (or "turning gear") is the mechanism provided to rotate the
turbine generator shaft at a very low speed after unit stoppages. Once the unit is "tripped"
(i.e., the steam inlet valve is closed), the turbine coasts down towards standstill.
• Generator cooling
• While small generators may be cooled by air drawn through filters at the inlet,
larger units generally require special cooling arrangements. Hydrogen gas cooling, in an oil-
sealed casing, is used because it has the highest known heat transfer coefficient of any gas and
for its low viscosity which reduces wind age losses.

12. Advantages
1) Economical for low initial cost other than any generating plant.
2) Land required less than hydro power plant.
3) Since coal is main fuel & its cost is quite cheap than petrol/diesel so generation cost is
economical.
Disadvantages:
1. It pollutes the atmosphere due to production of large amount of smoke and fumes.
2. It is costlier in running cost as compared to Hydro electric plants.
3. The heated water that comes from thermal power plant has an adverse effect on the lives in
the water and disturbs the ecology.
