Dear Mango,<br>
<br>
Welcome to the wonderful world of micro-gasifiers!!!<br>
<br>
A quick response is that you seem to have far too much entry of
primary air. Quick trial by you to check this is to block most of
the primary air holes (one way is to put a couple sheet of flat
paper over the holes on the inside of the bucket, and only open ---
punch through --- a few holes in the paper). Or use outside
blockages to limit the entry of primary air.<br>
<br>
Please describe how you are igniting.<br>
<br>
Plesase send some photos (low resolution is best). And tell us
more about yourself, including location and objectives.<br>

<br>
I'm a newbie to the biochar/gasifier stove scene and I'm trying
out a few designs for backyard cooking and camping. I've got a 20
L paint can as the reactor, 1 cm diameter primary air holes all
over the bottom lid with a big 8 cm hole in the center, and 1 cm
secondary air holes on the sides near the top lid. Fuel is small
dry twigs laid horizontally up to 2/3 full. I've fired the can
before to burn off any coatings. <br>
<br>
I get tall flames coming out of the chimney for a few minutes,
then the flames go lower and copious smoke comes out. I've tried
running it with the lid closed with a chimney and the lid on a 3
cm riser, also using different wood but nothing changes. I have to
quench the can after 10 minutes because there's just too much
smoke. <br>
<br>
I'd love to figure out what's going on and I really appreciate any
insight from the list members. Thanks in advance. <br>
