摘要：
Soot precipitation from a vertical laminar hydrocarbon flame onto a rod mounted outside the flame and having the same negative potential as the burner is investigated experimentally. The voltage-current characteristics of the burner-rod-upper grid electrode system and the currents flowing to each of these elements are determined when both negative and positive potentials are supplied to the burner. The pattern of growth of the soot deposition on the rod with increase in the negative potential is studied. The following fundamental effect is revealed: there is no soot extraction when the burner potential is positive. The experimental results obtained are qualitatively explained.
