Investigation of Critical C/H/N/O Reactions in NOx Formation and Removal inNatural Gas Combustion. Annual Report, July 1990-June 1991

摘要

In the research program, the kinetics of NOx formation and removal in thecombustion of natural gas are being investigated. The program addresses uncertainties in the reaction mechanism and the kinetic parameters of NO formation and removal reactions and the coupling of these reactions with the hydrocarbon combustion reactions. During the past year, work has progressed in the following areas: (1) a laser diagnostic for CH3 radical was developed for use in kinetics experiments; (2) a detailed reaction mechanism for pyrolysis of methane and ethane was developed and evaluated; and, (3) a collaboration with other GRI researchers was established to develop a comprehensive reaction mechanism for natural gas combustion.
