How does soot form when burned?
Hello, how does soot form? What must be incompletely burned for soot to form? Can you give examples? (Does it occur from burning photos and clothes?)

Soot is pure carbon. If any hydrocarbon burns (candle wax, oil, petrol, gas) the molecule is split up and the atoms connect with oxygen. Therefore, in the combustion of, for example, propane water and CO2 is produced. However, some of the carbon does not oxidize, but rather depends on surfaces. It's called soot.
Soot is also combustible. This is one of the reasons why there is a chimney sweeping spot. Before there was, chimney fires were common, because the set soot eventually ignited.
You should have thought.
What is soot? This is an element that occurs everywhere in organic substances or in coal, oil, gas.

Unwanted soot[ Edit | Editing source code )
In combustion processes, so often occurs as an undesired product. Incomplete combustion, oily carbon blacks and aerosols are produced. Such soot (English Soot) has shown the potential in animal testing to trigger cancer . However, the risk of cancer causes the incomplete combustion of Polycyclic aromatic hydrocarbons (PAH).
In oven heating as a product of incomplete combustion soot in the chimney tube settles and can be combined with tar the fireplace lead. To prevent this, the chimney sweep (smooth catcher) regularly the fireplace inner walls with a hard metal brush.
The Diesel in exhaust gases of motor vehicles Diesel engine has a similar composition, contains PAK as a function of the aromatic content of diesel and is therefore an air pollution . The better the atomization of the diesel during injection, the smaller and more resistant (and thus more risky) are the soot particles.
A study published in 2020 concluded by climate simulations that the cloud formation changed by soot particles Reheating contributes. [30] [31]
