Question

Coal tar fuels are liquid obtained by blending coal tar distillation products such as carbolic oil, naphthalene oil, creosote oil, anthracene oil and medium pitch. A sample of elemental analysis shows 85.9% C, 6.3% H, 1.2%S, 5.5% O and 1.1%N. If this fuel is burned in excess air at 30℃ and 755 mmHg with 90% RH, it produces a burner gas containing 10.64% CO₂, 3.19% CO and 0.64%H₂. Assuming negligible N and S. Calculate a) %excess air; b) Complete Orsat analysis of the burner gas; c) m³ stack gas.
