Regulates heat of flame and prevents soot
WebJul 11, 2024 · 6. Yes there are flames that don't produce smoke, but the reasons are complicated and depend on the conditions of the flame as well as the key fuel creating the flame. The obvious example of a smokeless flame is hydrogen. Pure hydrogen burns in oxygen to generate water and there is no way the normal things that make up smoke can … Soot is a mass of impure carbon particles resulting from the incomplete combustion of hydrocarbons. It is more properly restricted to the product of the gas-phase combustion process but is commonly extended to include the residual pyrolysed fuel particles such as coal, cenospheres, charred wood, and petroleum coke that may become airborne during pyrolysis and that are more p…

WebFlames used were of the standard variety or were slot flames, where the plume is basically restricted to two dimensions. Slot flames heat the fuel stream more slowly, so soot would be expected to form later and mature less rapidly. The use of these flames let us explore the effect of residence time on soot formation.
