The energy contained in the water being blown down is the liquid enthalpy of water at saturation temperature at boiler pressure. In Example 3.14.1, the boiler pressure is 10 bar g, and from steam tables, hf is 782 kJ/kg. So the rate at which energy is being released from the boiler is: 782 kJ/kg x 6.2 kg/s = 4.85 MW.
