pressure is transferred into steam by the
application of
heat.
•Working
The chemical energy convert into the heat
energy by the combustion process which
Is absorb by the boiler

3. Types of Boiler
Fire Tube boiler Water Tube boiler
Package Boiler Others
Boiler

4. Fire Tube Boiler
• Fire in tube or hot gas send
through the tube and boiler
feed water in shell side.
• Fire tubes submerged in water
Apllication
• It is used for small steam
capacities.
Marits
• Low capital cost and fuel
efficient(82%)

5. Water Tube Boiler
• Water flows through the tubes
and water tubes surrounded
by hot gas
Application
• For steam range 5.5 to 130
T/hr
• Used for power plant
Merits
Used as high capacity steam
boiler

6. Package Boiler
• It is comes as a complete
package that’s why it is called
package boiler. It is generally
shell type with fire tube
design.
• Large number of small
diameter tubes leading to good
heat transfer.
• It has higher thermal
efficiency compared to other
types of boilers.
