Superheated steam - Wikipedia

Superheated steam is steam at a temperature higher than its vaporization point at the absolute pressure where the temperature is measured.. Superheated steam can therefore cool (lose internal energy) by some amount, resulting in a lowering of its temperature without changing state (i.e., condensing) from a gas, to a mixture of saturated vapor and liquid.If unsaturated steam (a mixture which

DRAFT BOILER/FEEDWATER GUIDELINES

In a steam boiler system, there are three potentially destructive elements: oxygen, carbon dioxide, and solids. 2.2.2 As the boiler water is heated and changes to steam, free oxygen is released, carbon dioxide is released from the solids, and the solids drop out (precipitate). 2.2.3 As the steam is used in the end process, it cools and condenses
