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 ...
When steam has reached this equilibrium point, it is referred to as saturated steam. Superheated steam or live steam is steam at a temperature higher than its boiling point for the pressure, which only occurs when all liquid water has evaporated or has been removed from the system. [6]
An enthalpy–entropy chart, also known as the H–S chart or Mollier diagram, plots the total heat against entropy, [1] describing the enthalpy of a thermodynamic system. [2] A typical chart covers a pressure range of 0.01–1000 bar , and temperatures up to 800 degrees Celsius . [ 3 ]
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, in some steam engines, and in processes such as steam reforming. There are three types of superheaters: radiant, convection, and separately fired.
Most computerized databases will create a table of thermodynamic values using the values from the datafile. For MgCl 2 (c,l,g) at 1 atm pressure: Thermodynamic properties table for MgCl 2 (c,l,g), from the FREED datafile. Some values have truncated significant figures for display purposes. The table format is a common way to display ...

Description: Blue lines indicate vapor quality, mass percentage in the saturated mixture that is in gas phase . Black lines indicate pressure in pounds per square inch . Grey lines indicate specific volume in square feet per pound-mass of steam
Convection (cooking in a hot-air environment, without feeding in additional steam) - temperatures range from 30 to 250 °C (86 to 482 °F) or 300 °C (572 °F), depending on the model. Superheated steam (a combination of the two methods named above) - temperatures range from 30 to 250 °C (86 to 482 °F) or 300 °C (572 °F).
