Abstract

Combustion scientists and engineers have for a long time been interested in understanding the processes leading to the formation and disappearance of soot in flames. The practical reasons for developing a capability of predicting soot concentration were mainly connected with the effects of soot upon the radiative emission from furnace flames, and the clean combustion of hydrocarbon fuels in furnaces and gas turbines. More recently new interest has been generated by the concern over health effects of soot and polycyclic aromatic hydrocarbon species, the latter of which condense in the flue gas to form submicron-size aerosols. A major research program on the formation of particulates in flames, their emission and effects on human health, is in progress at M.I.T. under the sponsorship of the National Institute of Environmental Health. Investigations under this program include flat flame and stirred reactor studies of hydrocarbon vapor pyrolysis and the kinetics of formation of PAH and soot in pyrolyzing liquid fuel droplet streams. Parallel with these bench scale experiments detailed studies are carried out on turbulent diffusion flames using the M.I.T. Combustion Research Facility. In these flames the thermal and chemical environment of industrial flames is closely simulated.
