In this
video you can see two of my
biochar methods that I use, a 20liter TLUD gasifier that is gasifying stove pellets and its heat is used to heat up a 60 liter retort which sits inside an insulated 200 liter drum.
The smoke is passed through a cyclone filter followed by a condensation system to extract
wood vinegar.
The copper pipe from the condensation system was soldered using one of my smaller TLUD gasifiers.
