Desuperheating calculation
WebAlso note that energy is not being lost in the desuperheating process. Desuperheating simply creates more steam with fewer Btu's per pound by injecting water into the steam, which evaporates to produce steam with a lower enthalpy. In summary, the process of desuperheating converts a given amount of superheated steam into a greater amount of WebCondensation is usually assumed to begin when the bulk enthalpy reaches the saturated vapor enthalpy, which leads to discontinuity of heat transfer coefficient calculation in modeling. This paper addresses the discontinuity by showing the presence of condensation in desuperheating region when the wall temperature decreases below the saturation ...

Webdesuperheating process comes to a halt. When the steam velocity is too low, 'water droplet fall-out' occurs and a pool of water is formed which runs along the bottom of pipe. At this point good contact between cooling water and the steam is lost and effective desuperheating will not occur. By following the guidelines presented WebSteam Desuperheating Calculation.
