Abstract
The engine certification emissions data from a CFM56 single-annular combustor (SAC), the CFM56 dual-annular combustor (DAC), the CF6-80C SAC and the CF6-80C SAC low-emissions configuration (LEC) were used to show the following:
(1) NOxEI can be correlated as a function of P3 and T3.
(2) There is a unique relationship between NOx, CO and unburned hydrocarbons (HC).
(3) NOx, CO and HC for engine operating points can be predicted reasonably well through “single reactor” modeling. However, the resulting NOx/CO/HC relationship is not as well predicted indicating need for further improving the semiempirical methodology.
