A coal which has complete analysis of 86.86% C, 4.44% H, 1.9% O, 1.0 N, 5% ash and 0.8% S. is burned with excess air. Air is supplied dry at 25°C and 760 mm Hg. Analysis of the refuse shows 60% C and 40% ash. Partial orsat analysis of the stack gas (200° C, 755 mm Hg) shows 8.05% CO2, 2.42% CO and 2.9% H2. Calculate: a. (15 points) % excess O2 b.
