  2. Combustion - Wikipedia

    en.wikipedia.org/wiki/Combustion

    The flames caused as a result of a fuel undergoing combustion (burning) Air pollution abatement equipment provides combustion control for industrial processes.. Combustion, or burning, [1] is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.

  3. Soot - Wikipedia

    en.wikipedia.org/wiki/Soot

    Soot forms during incomplete combustion from precursor molecules such as acetylene. It consists of agglomerated nanoparticles with diameters between 6 and 30 nm . The soot particles can be mixed with metal oxides and with minerals and can be coated with sulfuric acid .

  4. Charring - Wikipedia

    en.wikipedia.org/wiki/Charring

    Charring is a chemical process of incomplete combustion of certain solids when subjected to high heat. Heat distillation removes water vapour and volatile organic compounds from the matrix. The residual black carbon material is char, as distinguished from the lighter colored ash.

  5. Endothermic gas - Wikipedia

    en.wikipedia.org/wiki/Endothermic_gas

    This gas is the product of incomplete combustion in a controlled environment. An example mixture is hydrogen gas (H 2 ), nitrogen gas (N 2 ), and carbon monoxide (CO). The hydrogen and carbon monoxide are reducing agents , so they work together to shield surfaces from oxidation.

  6. Tobacco smoke - Wikipedia

    en.wikipedia.org/wiki/Tobacco_smoke

    Tobacco smoke is a sooty aerosol produced by the incomplete combustion of tobacco during the smoking of cigarettes and other tobacco products. Temperatures in burning cigarettes range from about 400 °C between puffs to about 900 °C during a puff.

  7. Crankcase dilution - Wikipedia

    en.wikipedia.org/wiki/Crankcase_dilution

    Crankcase dilution is a phenomenon of internal combustion engines in which unburned diesel or gasoline accumulates in the crankcase.Excessively rich fuel mixture or incomplete combustion allows a certain amount of fuel to pass down between the pistons and cylinder walls and dilute the engine oil.

  8. Unburned hydrocarbon - Wikipedia

    en.wikipedia.org/wiki/Unburned_hydrocarbon

    Further, some regions of the combustion chamber may have a very weak flame, that is, they have either very fuel-lean or very fuel-rich conditions and consequently they have a low combustion temperature. These regions will cause intermediate species such as formaldehyde and alkenes to be emitted. Sometimes the term "products of incomplete ...

  9. Carbon black - Wikipedia

    en.wikipedia.org/wiki/Carbon_black

    Worker at carbon black plant, 1942. Carbon black (with subtypes acetylene black, channel black, furnace black, lamp black and thermal black) is a material produced by the incomplete combustion of coal tar, vegetable matter, or petroleum products, including fuel oil, fluid catalytic cracking tar, and ethylene cracking in a limited supply of air.
