Some limiting oxygen concentrations for diffusion flames in air diluted with nitrogen

摘要: Abstract Fuels have been burned at the surface of a porous hemispherical burner stainless steel, and nitrogen concentration required to extinguish flame has determined. Results are given for number fuels in terms limiting oxygen index [O 2 /(O + N )], it found that values close those obtained pre-mixed flames involving fuel stoichiometric proportions Calculations adiabatic temperature mixtures with indicate limit is primarily determined by temperature.
