(chemistry)
A faint, luminous phenomenon observed when, for example, a mixture of ether vapor and oxygen is slowly heated; it proceeds by diffusion of reactive molecules which initiate chemical processes as they go.

It can also be inferred from the rise in the HRR waveform and in the absorbance waveform that a cool flame developed prior to the main combustion period (regions B and C).
An examination of the absorbance waveforms indicates that under all the experimental conditions absorbance increased concomitant with the heat release produced by a cool flame and decreased simultaneously with the rise in heat release from the main combustion.
In previous combustion experiments aboard the space station, researchers observed cool flame burning behaviors not predicted by models or earlier investigations.
Note that this is also true in the presence of a cool flame, even if the cool flame behavior is not retrieved.
They've been "Keepers of the Flame'' since 1971 -- the cool flame of the uplifting and soulful music of traditional New Orleans jazz.
Seyla's seasoned solo dance to "The September of My Years," so revealing in its spareness, not only melts the audience but also Farmer's cool flame.
Basic venting principle is to cool flame gases within a special stainless steel mesh filter leading to a reduction of expanding gas volume as it extinguishes the flame.
The lean fuel mixtures, studied in a cylinder roughly 30 centimeters in diameter, generated unusually cool flames with about one-hundredth the power of a common match flame, says project scientist Karen J.
