Combustion of fuel vapor-drop-air systems: Part II—Spherical flames in a vessel

摘要: Abstract The burning characteristics of fuel vapor-drop-air systems (propane-kerosene drop-air systems) have been studied using a cylindrical combustion vessel, 58 mm deep and 148 in diameter, with centrally located spark gap. As the case burner flames reported previous paper, small amount kerosene drops added to propane-air mixture intensities process, raising maximum pressure for an overall fuel-air ratio shrotening time reach from ignition. In addition, both propagating velocities flame are markedly accelerated by very added. combustion-promoting effects more prominent leaner mixtures get less as becomes richer beyond stoichimetric. An optimum value exists quantity mixture.
