ConclusionConclusion

3. A boiler is a closed vessel
in which water or other
fluid is heated. The heated
or vaporized fluid exits the
boiler for use in various
processes or heating
applications, including
boiler-based power
generation.

ADVANTAGES
Fire tube boilers is so easy to use, operate,
clean & maintain.
 Fire tube boilers can be used in small scale
industries.
 Fire tube boiler is relatively cheaper than
water tube boiler.
 Steam can be generated at very high
pressure in water tube boilers.
 Steam can be raised more quickly.
 Bursting of one or two tubes does not
affect the boilers very much.
 A good & rapid circulation of water can be

19. • The efficiency of heat transfer
is bad enough in fire tube
boilers.
• Water treatment is very
essential for water tube boilers.
• Maintenance cost is high.
• The water level must be
watched very carefully during
operation of a water tube boiler.
DISADVANTAGES

20. Boilers are basically used to
generate steam for driving
turbine to generate electricity,
steam used for air conditioning
system, driving steam engines.
Some of the boilers used to run
ships using super heated steam.
Smaller boilers are used to
generate power to run cars.

21. Conclusion : -
In this time Boiler is a only way to get
cheap working substance to produce
the energy. Some time It’s become very
useful for many purpose of work.
