Question
A fuel gas has the following composition by volume; Hz. 20%; CH4, 2%; CO.
24%; CO2, 6%; O2, 3%; and N2, 45%. If 25% excess air is supplied, calculate the
mass of air at 0°C and 1.01325 bar (N.T.P) actually supplied for the combustion of
1 m° of this gas and also the percentage composition by volume of dry flue gases.
Take the specific volume of air at 0°C and 1.01325 bar as 0.7734 m'/kg. (%
composition of air by volume: N2. 79; 02, 21).
