Oct 08 2004 studies have been done in the paper industry that suggest that desuperheatedsteamis more effective in thedrum dryersin the paper machine note that i said effective not efficient overall heat transfer coefficients using only saturatedsteamare higher and seem to outweigh the decrease in temperature driving force
Steamtables contain values such as enthalpy h specific volume entropy s etc for saturatedsteam100 dry and for saturated water 0 dryness but typically not for wetsteam these can be calculated by simply considering the ratio ofsteamto water as described in the equations below
