WebAs in the previous example (2.3.4), the specific enthalpy of dry saturated steam (h g) at 1 bar g is 2 706.7 kJ/kg. The actual total enthalpy of the steam is greater than the total enthalpy (h g) of dry saturated steam at 1 bar g. The steam is therefore not only 100% dry, but also has some degree of superheat. WebThe maximum heat energy - enthalpy - in the water (condensate) at atmospheric pressure and 100 oC is 419.0 kJ/kg. Evaporation energy of water at the final condition at atmospheric pressure is 2257.9 kJ/kg. The flash steam generated can then be calculated: w = ( (670.9 kJ/kg)- (419.0 kJ/kg)) / (2257.9 kJ/kg) = 0.11 (kg flash steam / kg condensate)
