Thermal Field Characteristics with Alternative Fuels in Advanced Power Generation

David G. Lilley

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:

  1. Type of fuel amounts specified via C-H-O-N-S amounts and/or molar (volume) or mass fractions of multi-component fuels
  2. Different equivalence ratios
  3. Type of oxidant (air or oxygen)
  4. With and without limited dissociation of CO2 and H2O, and more detailed dissociation reactions
  5. 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
  6. The inlet temperatures of the fuel and oxidant streams individually are specified
