Smoke is a collection of tiny solid, liquid and gas particles. Although smoke can contain hundreds of different chemicals and fumes, visible smoke is mostly carbon (soot), tar, oils and ash. Smoke occurs when there is incomplete combustion (not enough oxygen to burn the fuel completely).
Smoke is a suspension [3] of airborne particulates and gases [4] emitted when a material undergoes combustion or pyrolysis, together with the quantity of air that is entrained or otherwise mixed into the mass.
Smoke is a visible collection of a variety of solid, liquid, and gas particles left unburned during the combustion process. (Figure 1) It is possible for smoke to contain a large number of different chemicals and fumes, although visible smoke is mostly carbon or soot, tar, oils, and ash. [2]
Mar 12, 2024 · Key Takeaways. Smoke from a fire results from the evaporation of volatile organic compounds in wood as it heats up. When these compounds reach a high enough temperature, they ignite, turning into carbon dioxide and water vapor, which causes the smoke to disappear as these byproducts are invisible.
May 3, 2018 · Smoke consists of gasses and airborne particles produced as a result of combustion or burning. The specific chemicals depend on the fuel used to produce the fire. Here is a look as some of the principal chemicals produced from wood smoke.

Jul 11, 2011 · Smoke is defined as the mixture of gaseous and particulate matter produced in a fire, and includes the air entrained into the fire plume. The formation of soot particles in diffusion flames and how smoke particles are formed is discussed.
Smoke is a homogeneous mixture of small particles that are created when hydrocarbons are burned, as well as water vapor and other gases, such as carbon dioxide, carbon monoxide, nitrogen...
