You have any experiences on this?<br>

If you made notches in the bottom of each stacked briquette (part of the combustion chamber) this might draw in pre-heated secondary air. But modify the press kit to make the necessary indentations.<br>

I was using a similar technique, where the sticks were inserted from<br>
underneath of the horizontally laid briquettes with the vertical hole in the<br>
middle (same thing as a sawdust stove). It kept the flames going all the<br>
time.<br>
