Thanks for the thumbs up.
Don, good forensic work
In the pic it shows 25c, ambient. This is after about 50km of drive, and temps will soon start riseing, and me looking for a filling spot.
This guage requires some skill to master. The thing is l have a insulated hopper that acts a whole lot different thain most others. Mainly, once its hot and neads a refill, it will not cool eaven when refilled. So, l first reaload when temps rise from 20-60c. Second, l reload when temps rise 60-80c. Third 80-100c, 4th 100-120c and then l run out of scale.
Plans are to fix this, add a nother lair of sheet steel on the existing hopper wall, between the wall and insulation. Intake air will be drawn trugh.
I think l got the 75% figured out by now, now l need to smoothen the 25%
JO, thats what you are having. I always looked at a wood gasifier as a charcoal producer/charcoal gasifier combo
