Experimental Studies of Chemical Processes in a Model Gas Turbine Combustor
Composition and temperature within a model gas turbine combustor have been measured in a series of experimental investigations. Species measured include CO2, CO, O2, total HC, NO, NO2, and particulates. The primary effort was devoted to the understanding of the process controlling the emissions of CO, HC, and NO. CO and HC levels are fixed by the thermal quenching of their oxidation reactions in the dilution zone of the combustor. NO levels are determined by the kinetics of formation and are strongly influenced by the maximum local temperature. The chemical kinetics of the controlling reactions should allow tailoring of combustor temperature-time characteristics in a manner to control the emission of all three species simultaneously.
