2. Calculate the stoichiometric air-fuel ratio for the combustion of a sample of dry anthracite of the following composition by mass: C = 90 %; H2 = 3%; N2= 1%, Sulphur = 3%; ash = 3% If 20 per cent excess air is supplied. Determine: (1) Air-fuel ratio (ii) Wet analysis of the products of combustion by volume. 3. The following is the analysis of a supply of coal gas: H2 = 49.4%; CO = 18%; CH4 = 20%; C4H8 = 2%; O2 = 0.4%;N2 = 6.2%, CO2 = 4%. (1) Calculate the stoichiometric A/F ratio. (ii) Find also the wet and dry analyses of the products of combustion if the actual mixture is 20% excess air
