Abstract
The ionized state in a flame propagating in a stoichiometric propane-oxygen mixture was investigated by a laser light scattering method. The charged particles, H-ions, C-ions or O-ions and free electrons, having an anomalously high temperature from 104 to 105 K were observed on both sides of the flame front, i.e. in the front of the flame as well as behind it, where the adiabatic combustion temperature should be about 3000 K. The results suggest that the measured values of the electron and ion temperatures as well as those of the electron density fluctuate over a wide range.Keywords
