A furnace is fired with fuel oil containing 86% C, 1%N, and 0.1%S with a calorific value of 46.4 MJ/kg. Air is supplied at 25°C, 740 mmHg and saturated with water. Average analysis of the stack gas shows 10.62% CO2, 1.17% CO, 6.34% O2 and 81.87% N2. The stack gas leaves at 400°C and 765 mmHg. Calculate: (Round everthing to 4 decimal places and make a basis) a. % excess air b. complete analysis of fuel oil c. m3 air/kg oil d. m3 stack gas/ kg oil
