Boiler Mountings, and Boiler Accessories: Engineering: Stanford University
Definition of Boiler:
The equipment used for producing steam is called Boiler or Steam Generator. Or it is also
defined as “ A closed vessel in which steam is produced from water by the combustion of fuel.”
The steam generated is used for:
Power generation
Heating
Utilization in industries like chemical industries, sugar mills, etc.
Working Principle of boiler:
The working principle of the boiler is very simple. Let’s understand it with a real-life example.
For bathing, especially in winter, you need to heat water so you should not feel coolness around
you.
but have you seen that when the temperature of the water increases beyond its saturation state, it
starts vaporizing? However, at home, you cannot collect the steam but in the industries, that
steam is used to generate electricity.
Now lets under What the working Principle of boiler is?
The boiler is a closed vessel that stores the water in it. Apart from water, boiler mountings and
boiler accessories are also present which increases the efficiency of the boiler which are
explained below. The Fuel(coal) is generally used as a furnace to heat the water present in the
boiler shell.
The hot gases from the furnace touch the surface of the boiler shell and thereby steam is
generated inside the shell which on further operations can drive the turbine. The driving of the
turbine leads to the generation of electricity which will be used for various purposes.
This is the working Principle of Boiler. Now, let’s classify the boilers…
Classification of Boiler:
The boilers may be classified as follows:
1. Horizontal, Vertical and Inclined Boilers
2. Externally Fired and Internally Fired
3. Fire-tube boiler and Water-tube boiler.
4. Natural circulation and Forced Circulation
5. High Pressure and Low-Pressure boilers
