methane is burned with dry air. the molar analysis of product is:

 

_CO2 =9.7%

CO = 0.5%

_O2 = 2.95%

N₂ = 86.85%

 

xCH₄ + yO₂ +y(3.76)N₂ -> 9.7CO₂ +0.5CO +2.95O₂ + zH₂O +86.85N₂

 

1. deternine x, y and z
2. calculate the air-fuel ratio (FAR)
3. determine the equivalent ratio and the percentage of excess air
