SUMMARY
The adiabatic flame temperature of methane when combusted with air can be calculated using the balanced reaction equation: CH4 + 2O2 + 7.43N2 → CO2 + 2H2O + 7.43N2. The formula for calculating the adiabatic flame temperature (Tf) is Tf = To + (nΔHc / ΣnCp), where To is the initial temperature (298 K), n is the number of moles, ΔHc is the heat of combustion of methane, and ΣnCp represents the thermal capacities of the products. This method provides a precise way to determine the flame temperature resulting from methane combustion.
