Steam Boiler: Saturated Steam VS Superheated Steam. Once the boiling point is reached, the water’s temperature ceases to rise and stays the same until all the water is vaporized. The water goes from a liquid state to a vapour state et receives energy in the form of “latent heat of vaporization”.
Even though Most boilers produce steam to be used at saturation temperature; that is, saturated steam. IBA provides Superheated steam boilers that vaporize the water and then further heat the steam in a superheater.
I could understand the concept of superheated water but superheated steam is Stack Exchange Network Stack Exchange network consists of 175 Q&A communities including Stack Overflow , the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.
Jul 11, 2018 · boilers, both before and after the switch from saturated to superheated steam. Waste Heat Saturated and Superheated Steam Boiler – Selnikel These type of boilers generate steam by recovering heat in the flue gas of facilities and significantly contribute energy efficiency of plant.
If one pound of superheated steam enters the same cylinder, it would have to be superheated to a point where its total heat is 1199 + 168 = 1367 B. t. u. or, at 200 pounds gauge pressure, superheated approximately 325 degrees if the heat given up to the cylinder walls were the same as for the saturated steam.
