[Stoves] flames touching pot

[John Davies]

Greetings all.

 

Something that I have accepted is that  the LPG gas burner has perfect
premixing, and mixing of air, resulting in no soot on the pot.

 

I was using one of these today, and observed how the flame spread out across
the bottom of the pot. The flames were touching the pot, but no soot. The
difference I see is that it is a blue flame, while our stoves tend to
produce a yellow flame.

 

The question is why the yellow flame produces soot , but not the blue one ?


 

Looking for answers,

John Davies.
