Below is a typical steam boiler diagram for dummy’s to understand with name of each component or boiler
part. First of all you should understand that there are many types and nomenclature of boilers. For

industrial boilers.
The main classification of boilers is in two categories i.e. water tube boilers and fire tube boilers. Fire tube
boilers are useful for small demands of steam and water tube boilers are useful for industrial level usage.

Lets first see some basic information about boilers. Boiler is a device used to generate steam at a desired
pressure and temperature by transferring heat energy produced by burning fuel to water to change it to
steam. Normally boiler is a combination of apparatus used for producing, furnishing or recovering heat
together with the apparatus for transferring the heat so made available to the fluid being heated and
vaporized.
The fluid is contained in the boiler drum called shell and the thermal energy released during combustion of
fuel is transferred to water and this converts water into steam at the desired temperature and pressure.
2. Fusible plug
6. Man and mud(sight)holes: Used to allow men to enter inside the boiler for inspection and repair.
7. Two safety valves: The commonly used safety valves are: Dead weight safety valve, Lever safety valve,
spring loaded safety valve and High steam and low water safety valve.
1. Economizer
2. Air Preheater
3. Superheater
4. Feed Pump
5. Steam Separator
6. Steam Trap
Advantages of economizer
2. If the boiler is fed with cold water it may result in chilling the boiler metal. Hot fed water checks it.
of fuel and air into a furnace at the desired velocities. The burner is the principal device for the firing of oil
and/or gas.
2. Mud Ring or Mud Drum: A typically cylindrical shaped space at the bottom of the water space. Sediment,
mud, and other impurities gather there.
4. Safety Valve: A spring loaded valve that automatically opens when pressure attains the valve setting.
5. Steam Separator: A device for removing the entrained water from steam.
6. Strainer: A device, such as a filter, to retain solid particles allowing a liquid to pass.
7. Sight Glass: A glass tube used on steam boilers to give a visible indication of the boiler’s water level.
8. Drain: A valve connection at the lowest point for the removal of all water from the boiler.
10. Ash Pit: The ash pit is the space where ashes accumulate under the fire. The ashes fall through the fire
grate into a (often) removable box.
11. Grate: Grate is a series of bars or narrow plates in the bottom of the fire box. The ashes fall through the
grate into the ash pit.
12. Pressure Gauge: Indicates the pressure of the steam in the boiler.
13. Fusible Plug: Operates as a safety valve when dangerous temperatures, rather than dangerous pressures,
are reached in a closed vessel.
14. Feed Check Valve: The high pressure feed water is supplied to the boiler through this valve. This valve
opens towards the boiler only and feeds the water to the boiler.
15. Steam Stop Valve: It regulates the flow of steam supply outside.
