In an experiment on a small oil-fired boiler, the steam is produced at 6 bar pressure, with dryness fraction 0.96. The 75 litres of water is converted into steam in 9.5 minutes. Then 10 litres of fuel oil with specific gravity 0.85 and calorific value 43125 kJ/kg is consumed in 11 minutes 25 seconds. The feed water temperature is 35°C. Determine the boiler efficiency and equivalent evaporation.
