Water enters a steam boiler at 10 bar pressure, 80°C temperature and 4 kg/s mass flow and leaves the boiler at the same pressure and 250°C temperature. Liquid fuel with a calorific value of 40,000 kJ/kg is burned with 80% efficiency. ; A) What is the thermal power transferred to the water in the boiler? B) What is the hourly fuel consumption of the boiler?
