A natural gas containing 82.0 mole% CH4and the balance C2H6is bunted with 20% excess air in a boiler furnace. The fuel gas enters the furnace at 298 K, and the air is preheated to 423 K. The heat capacities of the stack-gas components may be assumed to have the following constant values:
- Assuming complete combustion of the fuel, calculate the adiabatic flame temperature.
