That is incredible! The cleanest burn I have ever seen on the entire internet! Such a shame the hair dryer won't last too long. I think if you were going to install this into some kind of system a bouncy castle blower would last much longer and be quieter too. As for the flame, that is just awesome! Well done mate :)
hey jim here, WOW just watched the blue flame video, fantastic. interesting how the flame raises. whith more air and oil the fire extinguisher does not glow so much, maybe the air is cooling the flame. CHEERS and GOD BLESS
There are two Different types of combustion - diffusion, and premixed. Diffusion combustion is like a candle flame - you have a region of extremely rich fuel, right next to a region of air, and they diffuse into each other as the combustion occurs along that boundary. The problem is that you end up with fuel-rich combustion byproducts (soot particles) being formed, which give a yellow flame. In premixed combustion (such as a propane torch), you have the fuel and air already mixed before the combustion occurs, and you don't get any soot because you have no areas that are super rich. This burner type is based on adding air slowly a bit at a time to mix it into the fuel vapors, to create a premixed environment to achieve that blue flame. You want to add air gradually, so there's a gradient from super fuel-rich at the bottom to lean at the top, without adding enough air for actual combustion to occur too early (leading to a yellow sooty flame). More smaller holes can help make things more even, while still allowing enough air to get a good burn. My current version has 144 holes in it, six layers of 24 each.
@@MysticalDork Thank you, that was helpful. One question , there is no soot in air rich flame only when is air deficient flame, so does it burn clean with rich air supply even dough the flame is yelow? Thanks
@@VladFredK If the flame is yellow, it is producing soot particles, and that's incomplete (dirty) combustion. A little bit of yellow or orange tint near the bottom is usually OK because there's time for those soot particles to burn up, but in general, yellow = dirty. too much air supply too early (near the bottom) causes the flames to start too low, and they end up being yellow because you have rich fuel meeting lots of air, and you get a yellow flame. Farther up, you have less-rich fuel (had some air mixed in already) meeting the air jets, so it burns more cleanly. I'll put up a couple clips of my burner on my channel showing the beautiful pure blue flames I managed to achieve.

actually I used smaller air blower then last time so I think that is it but not sure.
I think the way to obtain a blue flame is to cool the flame(contradiction in terms)!
What’s the focus to get blue , more air or more fuel or size of air holes ?
size of air hole don't mater that much but its difficult to accomplish perfect mixture of fuel and air

@@MysticalDork so why don't you make video of your stove and how is build so other people can benefit from it. Thanks
What is castle blowers?
no idea
It's a high flow air pump for bouncy castles and inflatable kids rides.
