The results are given of an investigation into the production and electrostatic precipitation of combustion nuclei by an electrified propane-air flame. The apparatus consisted of a burner with a dc potential applied which was supported inside a grounded metal combustion chamber where the generation and removal of particles could be studied. A mathematical and experimental analysis of transient combustion nuclei concentrations inside the combustion chamber was carried out to evaluate the nuclei precipitation and production rates as a function of flame potentials and air flow rates. Two new theoretical equations containing production, precipitation, and flow parameters are derived to describe these transient concentrations. The constants of the equations were determined by experiment. These lead directly to the important parameters of nuclei production and precipitation rates, which are difficult to assess individually using previously known techniques. The experiments show that the concentration of combustion nuclei in the exhaust gas can be significantly decreased by the simple electrification of the flame. For combustion processes that generate aerosols, the method has the advantage of using the flame itself to affect the removal of the particles from the exhaust gases. Since combustion nuclei are receiving increased attention as air pollutants, this study could have important practical applications.
