A steam generator generates steam at an average rate of 50 000 kg/hour at a pressure of 3 000 kPa. The blow down is 10% of the steam generator's feedwater. The fuel consumption is 8 000 kg of coal per hour with a heating value 20 000 kJ/kg. What fuel saving in kilogram of coal per year will result from the installation of a blowdown heat-recovery system which will reduce the blowdown water temperature to 39 °C?
