Soot Formation Fundamentals

  • M. Ikegami


In this chapter topics relevant to soot formation during combustion are given, as well as the results of recent research centered around these. Sooting in flames has long been studied not only from scientific viewpoint but also for practical purposes, such as promotion of radiative heat transfer in boilers and furnaces and reduction of soot emitted as pollutant from combustors and diesel engines. In spite of exhaustive studies, the sooting phenomenon is still unclear and much unknown. This is because the sooting process is not slow enough to observe precisely what takes place in each step of fuel pyrolysis, nucleation, growth, coagulation and oxidation. Thus, difficulties are associated with direct verification of the proposed mechanisms and modeling concepts. To comprehend the essential aspects of the phenomenon, further progress in measuring techniques is necessary. At the same time more precise and advanced theoretical background should be given. Topics compiled in this chapter would respond to these requirements and perspective for understanding soot formation.
