What is the temperature of the steam?

According to pressure and temperature, all kinds of steam are divided into saturated steam and superheated steam. When the critical pressure is 22. 1MPa, the saturated steam temperature is 374℃; Superheated steam is higher than saturated steam.

When the number of molecules entering the space per unit time is equal to the number of molecules returning to the liquid, evaporation and condensation are in a dynamic equilibrium state. At this time, although evaporation and condensation are still going on, the density of steam molecules in the space no longer increases, and the state at this time is called saturation state. A saturated liquid is called a saturated liquid. Its steam is called dry saturated steam (also called saturated steam).

If the saturated steam continues to be heated by its steam, its temperature will rise and exceed the saturation temperature at this pressure. This kind of steam that exceeds the saturation temperature is called superheated steam.

Extended data

1, saturated steam has many advantages, especially at the temperature of 100℃(2 12℉) and above, which makes it an excellent heat source, some of which are as follows:

2. The use of superheated steam for supply and discharge has an obvious advantage, that is, steam will not produce condensed water when driving equipment, which can effectively avoid the risk of corrosion and erosion of equipment caused by carbonic acid. Disadvantages are as follows:
