Abstract:
Soot is a common by-product resulting from the
combustion of fossil fuels. Release of soot into the
atmosphere by combustion processes contributes to
environmental and health hazards and decreases the
efficiency of combustion processes since carbonaceous
particulates represent incomplete combustion. On the
other hand, soot formation is desirable in certain
applications such as industrial furnaces since the
presence of soot greatly enhances radiative heat
transfer. The challenge is to be able to control soot
formation for a specific task. Unfortunately,
understanding the mechanisms responsible for soot
formation remains a daunting task. The major steps in
soot formation consist of fuel pyrolysis, polycyclic
aromatic hydrocarbon (PAH) formation, particle
inception, coagulation, surface growth, carbonization,
agglomeration, and oxidation. The process of soot
inception is the least understood aspect of soot
formation.
