A black substance formed by combustion, or disengaged from fuel in the process of combustion, which rises in fine particles, and adheres to the sides of the chimney or pipe conveying the smoke; strictly, the fine powder, consisting chiefly of carbon, which colors smoke, and which is the result of imperfect combustion. See Smoke.
A black substance, mostly consisting of small particles of carbon, which can result from incomplete combustion and appear as smoke.
Carbon dust formed by incomplete combustion.
a fine, sticky powder, comprised mostly of carbon, formed by the burning of fossil fuels.
black powdery substance formed by the burning of coal.
Unburned particles of carbon derived from hydrocarbons.
very fine carbon particles that appear black when visible
Fine particulate mass, mostly carbon, that is emitted as a result of incomplete fuel combustion.
The combustible matter in the exhaust gas created as part of the normal engine combustion process typically observed as smoke. Mostly comprised of carbon.
Chemical name: Amorphous carbon Chemical formula: C See also: Chemical Table.
Black particles of carbon produced in a flame.
Fine particles formed from the incomplete combustion of fuels, can be powdery, oily or tarry based on the fuel source.
Carbon-containing particles produced as a result of incomplete combustion processes.
Very fine carbon particles that have a black appearance when released into the air.
Very finely divided carbon particles clustered together in long chains.
Soot, also called lampblack or carbon black, is a dark powdery deposit of unburned fuel residues, usually composed mainly of amorphous carbon, that accumulates in chimneys, automobile mufflers insides of smoke saunas and other surfaces exposed to smoke—especially from the combustion of carbon-rich organic fuels in the lack of sufficient oxygen. The combustion is thus incomplete. Lampblack is sometimes used only to refer to carbon deposited from incomplete burning of liquid hydrocarbons, while carbon black may be used to refer to carbon deposited from incomplete burning or pyrolysis of gaseous hydrocarbons such as natural gas.
