Soot is the primary cause of "ghosting", the discoloration of walls and ceilings or walls and flooring where they meet. It is generally responsible for the discoloration of the walls above baseboard electric heating units. The formation and properties of soot depend strongly on the fuel composition, but may also be influenced by flame temperature.

Soot, a carbonaceous particle formed during the incomplete combustion of hydrocarbon fuels, not only reduces combustion efficiency but also poses significant risks to human health and the atmospheric environment.

2025年2月28日 · To explore the role of fuel structures and hydrogen doping on soot formation under multi-fuel blending, a novel method combines the CoFlame code with ReaxFF MD to investigate the formation properties of soot in complex combustion systems .

• Soot is a small carbonacious particulate species • Soot forms on the rich side of nonpremixed flames as gaseous fuels are pyrolysed. • Soot particles consist of agglomerates of nominally round primary particles. • Primary particle sizes are around 50 nm. • Soot volume fractions are around 1-2 ppmv (up to 10-20).

2005年11月1日 · A review is given of recent papers on the phenomenology, kinetics, and mechanism of soot formation in hydrocarbon combustion; the effects of various factors on the formation of polycyclic...

2006年6月1日 · Diesel soot, one of the major environmental pollutants, is the finer particle produced during the high temperature pyrolysis or combustion of diesel fuel. Advances in the understanding of...

2023年9月15日 · Correlations between fuel properties and sooting propensity are drawn. C9/C9+ aromatics and late middle distillate strongly influence soot formation. Renewable fuels are essential to meet climate protection goals, especially for decarbonizing the existing vehicle fleet.

2025年1月22日 · Soot, which consists of tiny carbon particles, is generated when energy sources such as oil or wood are not completely burned. Soot particle filters, in turn, remove the nanometer- to...

2023年7月5日 · Soot from jet fuel combustion in aircraft engines contributes to global warming through the formation of contrail cirrus clouds that make up to 56% of the total radiative forcing from aviation.

Soot forms as a result of incomplete combustion. To achieve incomplete combustion instead of complete combustion, the fuel must burn at a lower temperature with a slightly reduced supply of oxygen. When the fuel burns, it breaks into small particles that include soot, which settles out as a dark powdery deposit.
