Scale is a white lumpy or powdery substance that gradually forms when the minerals contained in hard water is boiled and attached to containers (such as pots, pots, etc.). The main components are calcium carbonate, magnesium carbonate, calcium sulfate, magnesium sulfate, calcium chloride, Magnesium chloride and so on. The thermal conductivity of scale is very poor. If the scale formed in the boiler is too thick, the efficiency of the boiler will be reduced, and it will cause the boiler to burst and cause a boiler accident.
