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. Hz-2. N2-28. S-32, O3-32. Air contains 23.3% oxygen and 76.7% nitrogen If 20 per cent excess air is supplied determine: (1) Actual Air-fuel ratio (ii) Wet analysis of the products of combustion by volume (neglect the ash).
