A Hydrogen-Methane mixture is combusted in a furnace with 10% excess air. Hydrogen concentration is 50 vol\%. Consider the combustion reactions for hydrogen/air and methane/air as ideal one-step reactions. Heat capacity of the hydrogen at the ambient temperature =14.31kJ/kgK Heat capacity of the methane at the ambient temperature =2.226kJ/kgK Heat capacity of dry air at the ambient temperature =1.006kJ/kgK The mean heat capacity of the combustion products =1.172kJ/kgK Calorific value of hydrogen =141790kJ/kg, Calorific value of methane =55300kJ/kg, The ambient temperature Tfuel=Tair=27C [A] Asume the combustion in air can be expressed in one-step global reaction, write the reactions. [B] What is the fuel/air mass ratio? [C] What is the adabatic flame temperature
