Ethane (C2H6) is burned with 50% excess air. The reactions are as follows: C2H6 + O2  CO2 + H2O C2H6 + O2  CO + H2O 90% of the ethane entered the reactor was consumed. Of the ethane consumed, 75% reacted to form CO2, and the other 25% reacted to form CO. Calculate the composition of the flue gas.

Methane gas is burned completely with 30% excess air in a furnace operating at one atmosphere. Both the methane and air enter the furnace at 40ºC saturated with water vapor. The flue gas (furnace exhaust) leaves the furnace at 1000ºC. The flue gas then passes through a heat exchanger and emerges at 60ºC. If 260 mole/sec of methane fed to the furnace, how much heat is lost from the furnace, and how much heat is transferred in the heat exchanger?...
