I tried the flame hook, it's not bad as a system, it allows to retain large drops.
In addition, if I increase the oil flow on the ball, I no longer flood my second chamber, and the flame remains at the same size.

Then, I saw on the blue diagram a reheating of the air by the oil tank, is it used for something?

Good evening
I saw on the blue diagram a reheating of the air by the oil tank, is it used for something?

in my opinion ... no ... I would even tend to think that for better combustion it would be necessary to cool the air.

but I would also like to know why reheat the air?

yes but it risks "charcoal" on the flame hook : Cry:

Especially if the calories are "free" (recovery somewhere in the fireplace instead of an electric heater) combustion at a better efficiency with hot air. The vaporization of the oil drops will be more complete = less unburnt. The combustion will be faster and therefore the flame shorter.

It seems fairer to me, but no one forum haven't tried right?

Good, feedback on air heating:

it seems to be useless!

Its does not provide better spraying, and does not improve ignition

here is !

hi manoria
thank you for the feedback
I also give up if not much interest : Cry:
on the other hand I will try to heat the ventilated air with a recup on the stainless steel tube of the boiler to see ... to follow

ps: on the other hand what starts me c is that on the tests of the airtronic burner the results are better by bringing outside air ...? :?

For that to show a certain effectiveness, it is necessary that the air is hot like> 300 or 400 °. It's not that easy to do ... : Cry:
At startup, it is not too possible with recovery calories. I'm talking mainly about the air that allows combustion, the one that feeds the ball must not be too hot to not make coke (around 250 ° max).

Like the combustion air supply pipe passes through the boiler hearth before reaching the level of the ball.

To obtain this kind of T ° it will be necessary that the air heater is in the flame ...

I put back on the fire the question of heating the ball with a soldering iron resistance. for me, I had broken it before I could make conclusive tests.
Who tried?
