A fuel oil containing 70 % carbon by weight and the rest
combustible hydrogen and moisture is burned with excess air. The
flue gas analyzed 9 % CO2, 2 % CO, 3 % O2,
and 86 % N2. Determine the following:
The percentage of excess air. (15.1%)
The ratio of carbon to combustible hydrogen in the fuel on a
weight basis (3.35)
The ratio of the carbon to total hydrogen in the fuel on a
weight basis (3.19)
The percentages...
