Concentration Limits for n-Butane Low Temperature Flames

Abstract

Abstract The spontaneous ignition composition limits of four flame systems—cool, blue, yellow plume and transition—have been mapped out for the n-butane system in a dynamic flow reactor at atmospheric pressure. The cool and blue flames occur within as well as outside the fuel-oxidizer concentration limits for n-butane hot flames. Additional informationNotes on contributorsD.
