A pure, low molecular weight hydrocarbon gas is burnt in afurnace giving a flue gas containing
10.8% CO 2 , 3.8% O 2 and the remainder nitrogen. Calculate theatomic ratio, H/C, and from this
the formula of the fuel. Note that this analysis is on a drybasis.
2nd part:
Calculate the analysis of the flue gases resulting from thecombustion of ethane with 100%
excess air. Give the results on a dry basis.
