EVALUATION OF REDUCED CHEMICAL KINETIC MECHANISMS USED FOR MODELLING MILD COMBUSTION FOR NATURAL GAS

Abstract

A numerical and parametric study was performed to evaluate the potential of reduced chemistry mechanisms to model natural gas chemistry including NOx chemistry under mild combustion mode. Two reduced mechanisms, 5-step and 9-step, were tested against the GRI-Mech3.0 by comparing key species, such as NOx, CO2 and CO, and gas temperature predictions in idealized reactors codes under mild combustion conditions. It is thus concluded that the 9-step mechanism appears to be a promising reduced mechanism that can be used in multi-dimensional codes for modelling mild combustion of natural gas.
