An analytical model which considers gas-phase processes has been developed for gas turbine combustors. In the model the fluid mechanics of combustors are rather crudely approximated for reasons of mathematical tractability, and the perfectly stirred reactor constitutes the basic computational component of the model The analytical model was used to make predictions, for an actual combustor, which were then compared with internal and exit plane measurements of temperature, carbon monoxide concentration, and nitric oxide concentration. The internal data could be reasonably well approximated by the predictions, but the variations in exit plane values for certain changes in the operating conditions were incorrectly predicted. These discrepancies were shown to result, at least partially, from heterogeneous effects
