Question
Example 5.6 A liquid fuel containing 88 wt% C and 12% H is burned with air, comprising 21 vol% 02
and 79% N2, in a combustor. The combustion product is called "flue gas", and the flue gas leaving the
combustor is then passed through a desiccant column, to completely removed water from the flue
gas. The resulting dry flue gas is then passed through a gas analyser, to analyse for the composition
of the dry flue gas, and the analytical results are as follows: CO, 13.4% by vol., O2 3.6%, and N2 83.0%.
If the a mount of fuel fed into the combustor is 100 g, calculate the amount of the dry flue gas, in g,
and determine the percentage excess of O2 (note that N2 does not react with any other species)
Basis 100 g of feed (liquid fuel)
Thus, the feed comprises
88 g
12 g
