WebAs discussed above, superheated steam occurs when temperature of the steam is raised above the vaporization point. In this state of steam, all the liquid particles turn to gas. The enthalpy of superheated steam is much higher than saturated steam for a given pressure and temperature. It can be shown on Mollier diagram. WebThe addition of heat to steam at any point in the wet steam region causes the steam to dry, but always at the same temperature. The drier the steam, the closer it is to the dry saturated steam line. Set your preferences for these steam tables. Note: - You cannot use commas (,) as decimal points. Please use periods (.) Example: 1.02 not 1,02.

WebSuperheated steam is a form of steam at a temperature higher than its source liquid’s boiling point, aka vaporization point, under a given pressure. It is a relative state to something called saturated, or wet, steam. This kind of steam is one that just exceeds the boiling point of the source at a given pressure.
