Low-Power Turbopropulsion Combustor Exhaust Emissions. Volume 1. Theoretical Formulation and Design Assessment
Abstract
An exploratory development program was undertaken to formulate and develop a computerized, theoretical model to predict emissions characteristics of gas turbine engine combustors. In support of the model development, a number of experimental studies were conducted to provide information for structuring the formulation and for guiding its refinement. The programs were incorporated to provide data, unavailable in the combustion literature, on reaction rates under realistic burner operating conditions. The survey program was incorporated to provide baseline emissions characteristics for a number of existing gas turbine engine burners against which the generality of the model could be assessed. Indirect support of the model was provided by a comprehensive test program in which component design techniques for reducing low-power emissions by controlling the primary-zone equivalence ratio were evaluated using a research combustor. Control means included air-staging, fuel-staging, and premixing of fuel and air prior to their being introduced into the combustor. (Modified author abstract)
