A stream of natural gas containing 94% molar CH4, 3% C2H6, and 3% C3H8 is fed to a furnace at 25°C, with a volumetric flow rate of 1 m'/h, at a pressure of 1 atmosphere. In the furnace the fuel is burned with 50% excess air, which is fed at 150°C. Assume that the flue gases contain no unreacted hydrocarbons or carbon monoxide. Calculate: a. The lower heating value, VIC (kJ/mol) b. Adiabatic flame temperature, Tad (°C) c. The dew point temperature of the combustion gases, Tpr (°C)
