9. BASIC THERMAL POWER PLANT

10. Pulverizer
A pulverizer or grinder is a
mechanical device for the
grinding of many different
types of materials. For
example, a pulverizer mill
is used to pulverize
coal for combustion in the
steam-
generating furnaces of fossi
l fuel power plants.

11. Boiler Maintenance Department
A boiler or steam generator is a device
used to create steam by applying heat
energy to water.
Boiler

12. Boiler Auxiliaries
• Boiler Furnace : A boiler furnace is that space under a boiler in
which fuel is burned and from which combustion products pass
into the boiler properly.
• Economizer : These are mechanical devices intended to reduce
energy consumption, or to perform useful function such as
preheating a fluid.
• Super Heater : A super heater is a device used to convert
saturated steam or wet steam into dry steam used in steam
engines or in processes, such as steam reforming.
• Preheater : The function is to reheat the steam coming out
from the HP Turbine to a temperature of 540 Degree centigrade.

13. Turbine Maintenance Division
A steam turbine is a device that
extracts thermal energy from
pressurized steam and uses it to
do mechanical work on a
rotating output shaft.

14. Turbo Generator
Turbo Generator is a
combination of
Turbine directly
connected to an
electric generator for
the generation of
electric power.

15. Electrostatic Precipitator (ESP)
