Abstract
A calculation procedure is described that permits rapid calculation of fuel-air combustion with a very
large range of general fuels and conditions covering those for the use of alternative fuels in advanced
power generation. Calculations are made via Excel/VBA with immediate graphics of the parameter effects
on the results. A large range of useful results have been generated. Parameter variations include:
- Type of fuel amounts specified via C-H-O-N-S amounts and/or molar (volume) or mass fractions of
multi-component fuels
- Different equivalence ratios
- Type of oxidant (air or oxygen)
- With and without limited dissociation of CO2 and H2O, and more detailed dissociation reactions
- With "air" as the oxidant, the volume fraction of oxygen is specified, the other component of air may
be nitrogen or carbon dioxide or a combination of the two, and an amount of water may accompany the
inlet fuel and oxidant streams
- The inlet temperatures of the fuel and oxidant streams individually are specified
