Abstract
The low-pressure premixed laminar dimethyl ether/oxygen/argon flame with an equivalence ratio of 1.5 is studied using molecular beam mass spectrometry combined with synchrotron radiation photoionization technology. By measuring the photoionization efficiency curves, flame species are unambiguously identified, including those unstable molecules and free radicals. By measuring the signal intensities relative to the distances from the burner surface, mole fraction profiles of the major species and the major intermediates are derived. Meanwhile, the production and consumption pathways of those intermediates are analyzed.
