By: Marcial T. Ocampo
September 16, 2009
1) Input natural gas (fuel) analysis: % volume (same as % mol), molecular weights:
e.g. H2, CH4, C2H6, C3H8 … CO2, S, O2, N2, H2O moisture, ash.
2) Convert % volume to ultimate analysis % mass or weight (%C, %H2, % S, % O2, %N2, %H2O moisture, ash)
3) From the combustion equations;
C + O2 = CO2
S + O2 = S02
H2 + 1/2 O2 = H20
calculate the stoichiometric O2 in mols and lbs and that of N2 from air analysis. More »
