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.

ADVANTAGESFire 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
made.

• 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

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.

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.
