2 29 points Calculate the stoichiometric air-fuel ratio for the combustion of a sample of dry anthracite of the following composition by mass: C = 92.5 per cent; H2 = 3 per cent; N2 = 1 per cent; Sulphur=0.5 per cent; ash = 3 per cent. Molecular weights C-12, H2-2, N2-28, S-32, O2-32. Air contains 23.3% oxygen and 76.7% nitrogen If 20 per cent excess air is supplied determine: (i) Actual Air-fuel ratio (ii) Wet analysis of the products of combustion by volume (neglect the ash).
