A fuel oil is burned with air in a boiler furnace. The combustion produces 650 kW of thermal energy, of which 55% is transferred as heat to a boiler tubes that pass through the furnace. The combustion products pass from the furnace to a stack at 650°C. Water enters the boiler tubes as a liquid at 20 °C and leaves the tubes as saturated steam at 20 bar absolute. a. Define the system. What type of energy balance is needed?
