A gaseous fuel containing methane (CH₂) and ethane (C₂H.) is burned with excess air. The combustion reactions are shown below. The fuel enters the furnace at 25 °C and 1 atm, and the air enters at 200 °C and 1 atm. 100 mol of stack gas containing 5.321 % mol CO₂, 1.596 % mol CO, 7.317 % mol O₂, 12.239 mol % H₂O and the balance N₂ leaves the furnace at 800 °C a. Calculate the heat (kJ) transferred from the furnace. (-2765 kJ) b. If O₂ rather than air was fed to the furnace, would the exit gas temperature be higher, lower or the same? Give your reason.

Question
Transcribed Image Text:A gaseous fuel containing methane (CH₂) and ethane (C₂H) is burned with excess
air. The combustion reactions are shown below. The fuel enters the furnace at 25 °C
and 1 atm, and the air enters at 200 °C and 1 atm. 100 mol of stack gas containing
5.321 % mol CO₂, 1.596 % mol CO, 7.317 % mol O₂, 12.239 mol % H₂O and the balance
N₂leaves the furnace at 800 °C
a. Calculate the heat (kJ) transferred from the furnace.
(-2765 kJ)
b. If O₂ rather than air was fed to the furnace, would the exit gas temperature be
higher, lower or the same? Give your reason.
