Hi to all,
About the venturi burner (tube and cone) after the concentrator ring, i
forget to say that this burner only works for wood pellets.
I found that with wood sticks, wood chips or hard shells the burner does
not works.
The velocity of the gases and secondary air is more than the flame speed.

The reason, i think, is that for the same amount of primary air, the amount
of pyrolysis gases is more with pellets than with wood chips for example.
So, with the others combustibles, they needs more primary air velocity to
produce the same amount of pyrolysis gases.

But, if you go to the opposite direction, you can obtain more smoke with
the same amount of primary air. So, i will try with 6mm pellets with
shorter length (very short length) to see what happens.

This is the reason that 10 mm pellets lasts longer than 6 mm pellets (as it
is seen in a previous video in vimeo site)

Greetings
