Abstract:

The exploratory development effort to formulate and develop a computerized theoretical model to predict emission characteristics of gas turbine combustors and to identify, evaluate, and demonstrate improved combustion design techniques for increasing combustion efficiency at part power operating conditions was expanded to include detailed computer model and experimental data analyses. The generalized combustor computer program was used to predict exhaust emission concentrations from five different gas turbine engine burners predictions were then compared with measured data. In general, excellent agreement was achieved. In addition, a detailed comparative analysis of experimental data generated during the low-pressure and high-pressure test programs was conducted. From this analysis a phenomenological model for the premixing tubevirtual staging burner was prepared. Finally, a workhorse, variable geometry premixing burner was designed for reducing concentrations of exhaust emissions over the operating range from part to full power. Author
