2. 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, 02-32. 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).
