Steam Boiler: Saturated Steam VS Superheated Steam

Steam Boiler: Saturated Steam VS Superheated Steam. The water goes from a liquid state to a vapour state et receives energy in the form of latent heat of vaporization. As long as theres some liquid water left, the steams temperature is the same as the liquid waters. Steam is then called saturated steam.

How to Calculate Boiler Steam Flows | Hunker

Use boiler horsepower to calculate steam flow. Boiler horsepower is not related to mechanical horsepower. It is a boiler industry rating that predicates the amount of saturated steam a boiler will generate starting with water at 212 degrees Fahrenheit and 0 pounds per square inch gauge (psig--meaning atmospheric pressure) and ending with steam at 212 F and 0 psig.

Thermal Fluid VERSUS Saturated Steam - TT BOILERS

When using steam (or water) these high process temperatures are achieved by pressurising the steam (or water ). Dry saturated steam is both very efficient to carry heat and to deliver and transfer the heat. Saturated steam offers a very high specific heat content (kJ per kg steam) and thereby deliver a large amount of heat by a modest steam flow.

Superheated steam - Wikipedia

Saturated steam is steam that is in equilibrium with heated water at the same pressure, i.e., it has not been heated above the boiling point for its pressure. This is in contrast to superheated steam, in which the steam (vapor) has been separated from the water droplets then additional heat has been added.
