Working Principle of Boiler – StudiousGuy

Working Principle of Boiler. The working of a boiler typically depends on the principle of conversion of energy from one form to the other and the conversion of matter from one state to the other. Initially, when the water is poured into the chamber or into the boiler''s closed vessel, it is externally supplied with heat energy.
