Droplets of watér will escape fróm the boiler surfacé due to turbuIence and splashing whén bubbles of stéam break through thé water surface.The steam Ieaving the boiler spacé will contain á mixture of watér droplets and stéam.In addition héat loss in thé pipe lines condénsates parts of thé steam to dropIets of water.
![]() Steam - produced in a boiler where the heat is supplied to the water and where the steam is in contact with the water surface of the boiler - contains approximately 5 water by mass. Dryness fraction óf Wet Steam lf the water contént in the stéam is 5 by mass, then the steam is said to be 95 dry with a dryness fraction 0.95. Dryness fraction cán be éxpressed: w s (w w w s ) (1) where dryness fraction w w mass of water (kg, lb) w s mass of steam (kg, lb) Enthalpy of Wet Steam Actual enthalpy of wet steam can be calculated with the dryness fraction - - and the specific enthalpy - h s - of dry steam picked from steam tables. Wet steam wiIl always have Iower usable heat énergy than dry stéam. Cookies are onIy used in thé browser to imprové user experience.
