Abstract
The mechanism of air pollutant generation during combustion of gaseous fuels is simulated with ASPEN Plus process simulator release 9.1 -3 (1994). Based on the concept of minimization of total Gibbs free energy of the system, adiabatic flame temperatures for several stoichiometric fuel/air mixtures are calculated. Analysis of combustion products including air pollutants with concentrations as low as 1 ppb is carried out and compared with previous works. Sensitivity analysis to study the effect of changing reaction temperature and fuel/air ratio on pollutant concentrations are also carried out and the results are discussed. Detailed tables and various graphical resul ts are presented, demonstrating the powerful capabilities of ASPEN Plus in combustion modeling and air pollution studies.
