Steam has a dryness fraction of 0.97, while its degree of superheat (at the exit from super heater) is 66 C. from super heater) is 66 C.
Get price2015/3/17 · Step 1: Determine Properties of Steam Produced. Using the Steam Property Calculator, properties are determined using Steam Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow
Get priceAnswer (1 of 6): Water does not change its mass on going from liquid to gas, so to produce one ton of steam per hour you need one ton of water per hour, plus a safety margin to ensure that your boiler doesn't run dry.
