Write the overall reaction for the combustion of butane C4H1

Write the overall reaction for the combustion of butane (C₄H₁₀) with 120% theoretical air.

Percentage of Carbon in C4H10 = 48*100/(48+10) % = 82.76%

Percentage of Hydrogen = 100 - 82.76 = 17.24 %

Theretical Air required = 4.31(2.67C + 8H) = 15.468 kg of air /kg of fuel

Actual Air Supplied = 1.2* 15.468 = 18.562 kg/kg of fuel

Now since excess air is supplied there is no formation of carbon monoxide

C₄H₁₀ + 7.15O₂ -----> 4CO₂ + 5H₂O + 0.65O₂
