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’...
H.W.6.17. A boiler is supplied with coal gas of the following composition: 53.6% H2, 9% CO, 25% CH4, 3% C4H8, 0.4% O2, 3% CO2, 6% N2. If the air fuel ratio is 6.5/1 by volume, calculate the analysis of the dry products of combustion by volume.
Flue gas from a sugar mill furnace burning bagasse fibre in air contains 8.35% CO2, 15.5% H2O, 0.55% O2 and 75.6%N2. 130 kmol/min of the flue gas exits the furnace at 1300 C and 1atm and is used to generate steam in an adiabatic boiler (i.e. well-insulated heat exchanger). After exchanging heat with the steam, the flue gas leaves the boiler at 350 C and 1atm. Saturated liquid water at 75 C enters the adiabatic boiler tubes where it is...
