Abstract
Originally, studies of ionization in flames were motivated by the observation that in hydrocarbon flames, the ion concentration far exceeds the value expected if ionization were due to thermal processes alone(1,2) (see Table I). The objectives of these studies were to explain the source of nonequilibrium ionization and to explore links between flame ionization and the mechanism of flame propagation. An explanation of the source of flame ions was found in the process of chemi-ionization.(2) This led to further studies of the details of ionic reactions which occur in flames and of flame reactions which can be induced by the addition of foreign elements.
