Abstract
Flame spray pyrolysis is intensively developing as a promising method of nanoparticle synthesis. The experimentally measured chemical and thermal structure of the spray flame is critically needed as a validation target for simulations of the synthesis of nanoparticles in these spray flames. This paper presents an experimental study of the chemical and thermal structure of the flame produced by the SpraySyn burner. The spatial distribution of the main species is obtained by microprobe sampling in combination with orthogonal time-of-flight mass spectrometry. The temperature distribution is obtained by a micro-thermocouple technique. The presented species and temperature data are discussed in the context of their experimental uncertainties and the plausibility of the flame structure.
