8. AIR PREHEATER
• It is a device used in steam boilers to transfer
heat from the flue gases to the combustion air
before the air enters the furnace.
• Also known as air heater; air-heating system but
it is kept at a place near by where the air enters in
to the boiler.
• The purpose of the air preheater is to recover the
heat from the flue gas from the boiler to improve
boiler efficiency by burning warm air which
increases combustion efficiency, and reducing
useful heat lost from the flue.

10. SUPER HEATER
• A device which removes last traces of
moisture.
• It helps in reduction in requirement of
steam quantity.
• steam being dry reduces the mechanical
resistance of turbine.
• No corrosion at the turbine blades.

11. COOLING TOWERS
Remove heat from the water discharged from the
condenser so that the water can be discharged to
the river or re circulated and reused.
• Air can be circulated in the cooling towers through
natural draft and mechanical draft.

12. TURBINE AND ALTERNATOR
•A steam turbine is a mechanical device that extracts
thermal energy from pressurized steam, and converts it
into mechanical energy.
•An alternator takes this mechanical energy as input and
gives electrical energy as output.
