Superheated steam is steam with a temperature that is higher than the saturation temperature for a particular steam pressure. The saturated steam is described as superheated according to the degrees it has been heated to above the saturation temperature.
Superheated steam has more energy and can work harder than saturated steam, but the heat content is much less useful. This is because superheated steam has the same heat transfer coefficient of air, making it an insulator and poor conductor of heat.
A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, steam engines, and in processes such as steam reforming. There are three types of superheaters: radiant, convection, and separately fired. A superheater can vary in size from a few tens of feet to several hundred feet.

Superheated steam boiler. When water is boiled the result is saturated steam, also referred to as "wet steam.". Saturated steam, while mostly consisting of water vapor, carries some unevaporated water in the form of droplets. Saturated steam is useful for many purposes, such as cooking, heating and sanitation,
Steam Boiler: Saturated Steam VS Superheated Steam. Once the boiling point is reached, the water’s temperature ceases to rise and stays the same until all the water is vaporized. The water goes from a liquid state to a vapour state et receives energy in the form of “latent heat of vaporization”.
Mar 21, 2014 · The remaining water droplets that are suspended in saturated steam can themselves become steam. Superheated steam is important because it increases the efficiency of the boiler. In the power generation industry it serves an additional crucial function: “drying out” the steam.
