It can reduce the size of itself and increase the dryness of the steam (that is, the small amount of moisture) by reducing the moisture content of steam generated from the water heated by the heat of combustion in the combustion chamber. It provides a steam boiler that maximizes thermal efficiency and boiler efficiency by preventing the reduction to water (= condensation) and maximizing the heat transfer area. This place is designed for completing the technical challenges.
