Problem 4 A fuel gas has a composition by volume of: 50% H2 , 6% CO2, 4% N2 , 40% CO. The dry exhaust gas analysis (% by volume) of the actual combustion process indicates 9.2% CO2, 0% CO, some O2. Recall that for gases, volumetric composition is the same as molar composition. (a) What air/gas ratio (by volume) is required for stoichiometric combustion? (m? air/ m² fuel gas) (b) What air/gas ratio (by volume) has actually been used? (m’...
