  2. 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 ...

  3. Soot - Wikipedia

    en.wikipedia.org/wiki/Soot

    In some definitions, soot is defined purely as carbonaceous particles, but in others it is defined to include the whole ensemble of particles resulting from partial combustion of organic matter or fossil fuels - as such it can include non carbon elements like sulphur and even traces of metal.

  4. Fuel gas - Wikipedia

    en.wikipedia.org/wiki/Fuel_gas

    Incomplete Combustion Factor (ICF) – an empirical index that relates the composition of a gas to its tendency to burn incompletely in a gas appliance. [7] Dutton defined the ICF as: ICF = 0.64 × (W − 50.73 + 0.03 × PN) where W is the Wobbe index, MJ/m 3 ; PN is the volumetric percentage of C 3 H 8 plus N 2 in a three-component mixture.

  5. Carbon monoxide poisoning - Wikipedia

    en.wikipedia.org/wiki/Carbon_monoxide_poisoning

    Carbon monoxide has a higher diffusion coefficient compared to oxygen, and the main enzyme in the human body that produces carbon monoxide is heme oxygenase, which is located in nearly all cells and platelets. [6] Most endogenously produced CO is stored bound to hemoglobin as carboxyhemoglobin. The simplistic understanding for the mechanism of ...

  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. 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.

  8. Black carbon - Wikipedia

    en.wikipedia.org/wiki/Black_carbon

    Black carbon (BC) is the light-absorbing refractory form of elemental carbon remaining after pyrolysis (e.g., charcoal) or produced by incomplete combustion (e.g., soot). Tihomir Novakov originated the term black carbon in the 1970s, after identifying black carbon as fine particulate matter (PM ≤ 2.5 μm aerodynamic diameter) in aerosols ...

  9. Combustibility and flammability - Wikipedia

    en.wikipedia.org/wiki/Combustibility_and...

    The burning of a solid material may appear to lose weight if the mass of combustion gases (such as carbon dioxide and water vapor) are not taken into account. The original mass of flammable material and the mass of the oxygen consumed (typically from the surrounding air) equals the mass of the flame products (ash, water, carbon dioxide, and ...
