information about the secondary air inlet tubes measure

[FROMITALY]

I've made too many holes in each tube every three rows of holes 4 mm (about 30 per tube) so in total 60 holes

the second test is ok

seems to go a bit better the flames came out of the secondary

but they had little power (perhaps too many holes)

the tubes were almost secondary red (stainless steel) and then the temperature is ok

Maybe try again with 40 - 3mm holes? (20 in each pipe)

 

[FROMITALY]

ok try 40 holes 3 mm
currently the holes are arranged in three rows for pipe

okay o 'better put them on one or two rows

It is easier to drill more holes and than it is to remove holes. Try drilling just one row of 12 - 3mm holes on the bottom of each secondary tube (facing down). Test that and see how it works.

I also believe that it is important to have a lot of pre-heated air inside the stove as an accumulation do not know explain seeds

in my case the 30 mm tubes are small air goes directly to the holes in the tube and heated on the way

I reflect now because in addition to reducing the holes for me that you have to create a place accumulation of air inside the stove

Get rid of some of the 90 degree turns to improve air flow.

Did you try burning in the stove with this pipe configuration?

 

[FROMITALY]

no I have not tried this configuration
But I'm afraid that does not heat to air

Try it, but with less holes (12 x 3mm) in each secondary pipe.
