Flame Cap 'Corrugated Box' V2 Panel Kiln update

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!
