WebMay 8, 2012 · The equation of degree of superheat is: Degree of superheat = tsuperheat – tsaturation The tables of properties of superheated steam range in pressure from 0.006112 bar to the critical pressure of 221.2 bar. At each pressure, there is a range of temperature up to high degrees of superheat, and the values of specific volume, … In thermodynamics, superheating (sometimes referred to as boiling retardation, or boiling delay) is the phenomenon in which a liquid is heated to a temperature higher than its boiling point, without boiling. This is a so-called metastable state or metastate, where boiling might occur at any time, induced by external or internal effects. Superheating is achieved by heating a homogeneous substance in a clean container, free of nucleation sites, while taking care not to disturb the liquid.
