[Stoves] Is the Blue Whirl really a 'thing'

[Crispin Pemberton-Pigott]

Dear Tony V

From the article

"It is usually a very difficult process to burn liquid hydrocarbon fuels in a clean way with no soot production."

Was this written by someone who is unfamiliar with combustion?  How could such a statement be supported?  Liquid hydrocarbons are easily burned soot-free by providing the correct conditions.  Kerosene is an example of a hydrocarbon fuel.  Not only is it possible to burn it without any formation of soot, it can be burned without any flame!  The Japanese have led the field for some time (FLOX, it is called – flameless oxidation).

So the formation of a swirling blue flame brings these researchers from the past into the 80`s or 90`s.  FLOX moves past having any flame at all. Perhaps that will provide the next opportunity for a coding project.

Stay well
Crispin

Subject: [Stoves] Is the Blue Whirl really a 'thing'

Recently the news media has been popping articles about a new type of flame being called a Blue Whirl.

Is this really something new?
Is there some lessons here about rotation in a stove burn chamber of stove design?

The article is about liquid combustion, not wood gas.

Here's one example there are several buzzing the airwaves....
