Hi there. I've just done my first burn on the Flame Cap 'Corrugated Box' V2 Panel Kiln (which has a page on my website for more details).
Here are the results of the first burn:
- Built a hot fire (up to 784degsC measured with a laser thermometer near the end of the burn) and possibly all VOCs released.
- Layering was not perfect and the entire volume of the kiln was not used
- The forestry waste had minimal prior feedstock processing (cut into limb and branch lengths ~2m long but could be cut to 3m long which would be optimised for this kiln and still ergonomic
enough to move around) and loaded into the kiln like a dream. Compared to all the feedstock processing I undertook for the KTE and KTR, I wish I had built this kiln years ago!
- The fire was perfectly wind protected on a still day but a high level of caution was used, allowing plenty of distance between the kiln and me in between adding feedstock to minimise the
chance of burning my face
- Feedstock was not bone dry (presumably some above 15% moisture content (MC) but plenty of oily leaf from forestry waste was used intermittently throughout the burn which dried and pyrolysed
the feedstock during the burn with almost zero smoke
- In kiln quench worked well with biochar mixed during the quench until zero steam and smoke
- Pretty decent volume of biochar produced for the first test burn!
