From the table a value of 720.9 kJ is needed to raise 1 kg of water from 0 oC to the saturation temperature 170 oC.The heat energy (enthalpy of evaporation) needed at 7 bar gauge to evaporate the water to steam is actually less than the heat energy required at atmospheric pressure. 2,676 kJ/kg. Steam at atmospheric pressure is of limited practical use. It cannot be conveyed by its own pressure along a steam pipe to the points of consumption.At 7 bar gauge (absolute 800 kN/m2) - the saturation temperature of water is 170 oC.
