Development of stability diagrams of flame in diluted combustion

Diluted combustion is a process which leads to a reduction in emissions of greenhouse gases and other pollutants like NOX. In the scientific literature, information and design guidelines are available for standard fuels, such as methane or propane, but there is a lack of information for other fuels such as industrial by-products and gasification fuels (mixture of CH4, H2 and CO). The purpose of this work is to collect experimental data to characterize combustion features of various fuel blends in diluted combustion conditions. This paper reports the first series of experiments with methane, which serves as a reference fuel. A numerical study, using a detailed chemical-kinetic mechanism is shown to provide good overall agreement with experimental data
