Explain a fuel gas containing methane

Reference no: EM13208122

A fuel gas containing 90% methane (CH4), 5% acetylene(C2H2) and 5% butane gas(C4H10) by volume is fed to a furnace in which it is completely burned with 10% excess air. The fuel gas flow rate is 1000 m^3/h at 15 degrees Celcius and 250 kPa. The composition of the air (mole%) is 79% N2 and 21% O2.

Combustion Reaction:

CH4 + 2O2 ---> CO2 + 2H2O

C2H2 + (5/2)O2 ---> 2CO2 + H2O

C4H10 + (13/2)O2 ---> 4CO2 + 5H2O
