Working of Boiler – Explanation, Parts, Working Principle
The boiler is a closed vessel, where the water is stored. Hot gases are formed by burning fuel in the furnace. These gases are made to come in contact with the water vessel, the point where the heat transfer takes place between the steam and water. Thus, the boiler's basic principle is to convert water into steam with heat energy.
