How To Make Biochar In A Barrel. The pyrolysis layer will be smoldering, you can then see the biogas and smoke rising above that, once it reaches the air intakes and chimney it erupts into a flame vortex. The need for soap would indicate the presence of.
After creating the biochar, we then quench it with water from our onsite borehole. Pyrolysis can therefore happen in a heated barrel with the lid on and a couple of holes drilled in the side. We make our biochar in simple cone pits, without the need of a barrel or rocket stove.
Set aside with the stack.
I also packed it more sparsely into the barrel. Carefully load the small barrel into the larger barrel. To do this i tend to douse the whole thing with some water from a hosepipe then, wearing a big heavy fireproof glove, i drag the drum away from the remaining pile of biochar. The chunky biochar is then smashed up in an old rice bag to the desired size before we begin to inoculate it.
