Science, 1982
A potential problem associated with soot particles in the atmosphere is pointed out, namely, the catalytic activity of such particles for certain atmospheric chemical reactions, including the oxidation of sulfur dioxide to sulfate. Conversion of SO/sub 2/ to sulfate is widely recognized as a major source of acidity in clouds and rain water.

Effects of Soot Structure on Soot Oxidation Kinetics [PDF]
, 2011 Abstract : This project focused on the mechanisms of soot oxidation by O2. A two-stage burner was used. Soot was generated for ethylene, JP-8 surrogate (n-dodecane/m-xylene), m-xylene, and n-dodecane air premixed flames. Downstream, the soot-laden gases were passed through a secondary flat-flame burner where soot was burned out under fuel-lean or -rich

A mechanism for the formation of soot particles and soot deposits
Combustion and Flame, 1992The extent of the role of polycyclic aromatic hydrocarbon (PAH) species in the mechanism of soot formation has not definitely been determined. In previous work using a flat-flame, water-cooled, premixed burner burning ethylene-air flames we investigated the formation and destruction of PAH species up to five aromatic ring structures.

On the rate of combustion of soot in a laminar soot flame
Combustion and Flame, 1962Abstract Rates of combustion of soot were measured in a laboratory type laminar hydrocarbon gas flame. The mass flow rates of soot were determined together with the local temperatures and the partial pressures of the oxygen at successive stages of the reaction.

Soot From Fires: III. Soot Suppression
Journal of Fire Sciences, 1986The literature on soot suppression, in particular from fuels relevant to fires, has been reviewed. The efficient additives required for soot suppression from gaseous fuels are mainly metallic salts, typically barium. On the other hand, the reduction of the smoke formation tendency of polymeric materials has been achieved by an enormous variety of ...

Formation of Hydrocarbons and Soot
1996Hydrocarbons and soot predate NO x (Chapter 17) as pollutants from combustion. In earlier times, smoke from the factory smokestack was a sign of prosperity. In time it became a nuisance and finally a health concern. The remedy to the appearance of soot and smoke are the three “t’s” of combustion: time, temperature, and turbulence (Babcock and Wilcox ...

Temperature and soot concentration in a high soot density flame
International Journal of Heat and Mass Transfer, 1996Abstract The emissivity of a particulate flame which contains interacting soot particles of size parameters larger than Rayleigh limit and up to Penndorf extension is derived. The flame is assumed to be heavily charged with soot particles and radiation from the flame is mainly dominated by that emitted or absorbed by particles.

One primary advantage of ceramic vessels, in comparison to other containers, is that they can be placed directly over or in a fire to process its contents. There are, however, multiple ways that this can be done and many different processing strategies.

Progress in Energy and Combustion Science, 1983
In this article the toxicological effect of soot exposure on man is explored with emphasis on the role that soot may play in the induction of cancer and respiratory diseases. Soot may be defined as the product of the incomplete combustion of fossil fuels and other organic matter; the resultant soot particulate consists of finely divided carbon ...
