Incase anyone is interested in the Biochar burn I did the other day here’s how it worked for me (I was not sure what to expect- so feel like it might help others)
I used a biochar kiln, with an inner & outer sleeve. The inner sleeve has holes at the bottom and very top only.
The fuel was riddled woodchip (to stop too small particles blocking airflow)
1 You can see the gasses coming through the top airholes & burning off.
2 flames go pale/invisible
3 quenched char

@Hellybootwader Brilliant. How much biochar did you make from this kiln in one go? And how much water did you need to quench it?

I’ve only once helped with a cone pit burn for biochar and that took a ridiculous amount of water to quench it.

I still have some biochar left from that burn. I add it to the compost so it becomes inoculated by all the microbial life in there.

@Broadfork it was a small burn as I was still working out if the burn was right.
But probably about half a trug of woodchip would fit in to the kiln, and after it’s burnt it would be a bit less than half of that. It was about an hour to burn, & took a watering can’s (10L ish) worth of water to quench it- I used another half to be sure.
Then I added the worm run off to make sure the char was safe for storage.

@Hellybootwader I’m impressed. That’s very efficient and not time consuming either.

@Broadfork yep, it fits what we needed very well
