Extracted text: DExample 9.8. Calculate the stoichiometric air-fuel ratio for the combustion of a sample of dry anthracite of the following composition by mass: Carbon (C) =85per cent Hydrogen (H2 ) = 7 per cent Oxygen (02) = 2.5 per cent Nitrogen (N2 ) = 2 per cent Sulphur (S) = 0.5 per cent Ash = 3 per cent If 30 per cent excess air is supplied determine : () Air-fuel ratio (ii) Wet dry analysis of the products of combustion by volume.
