✦ Synopsis

Deposition of soot particles during any combustion process is very undesirable and can cause both mechanical and environmental problems. An investigation has been carried out of the deposition of soot on to both cooled and uncooled metal probes in rich ethene/air flames (q~ = 2.76 and 2.52) using a flat-flame, water-cooled burner. The processes by which soot particles move to the surface of deposition probes, and the way in which they adhere to the surface, have been explored. The results have shown that the temperature of the probe can have a significant effect on the deposition rates and the chemical nature of the deposits.
