The workings of a boiler are very simple and easy to understand. As we know, a boiler is a closed vessel where water is stored first. Fuel is burned in a furnace, and water is converted into hot gases. These hot gases come into contact with water vessels, where the heat of such gases transfers to the water. Hence, steam is produced in the boiler.
