Question
A fuel oil is burned with air in a boiler. Combustion produces 813 kW of thermal energy (heat), 65% of which is transferred as heat to boiler tubes that pass through the furnace. Combustion products pass from the furnace to a chimney at 550°C. The water enters the boiler as a liquid at 30°C and exits as a saturated steam at 20 bar (absolute).
(a) Calculate the rate (kg/h) of steam production.
(b) Use the steam tables to estimate the volumetric flow of the steam produced.
(c) What happens to the 35% of thermal energy released by combustion that is not used to produce steam?
