Charcoal Ring Kilns

Available in 5ft, 6ft, 7ft, and 8ft diameters, these kilns offer a straightforward, reliable way to produce high-quality charcoal. The smaller sizes are easier to handle and ideal for lower output or tighter access, while the larger kilns suit higher-volume production.
All sizes remain relatively portable and can be used individually or as part of a multi-kiln setup - allowing one kiln to burn while others are emptied and recharged for a more efficient workflow. Extension rings are available for selected sizes, allowing you to increase capacity at a later date while continuing to use the original lid. If you are looking to produce charcoal on a smaller scale or just for your own hobby production - take a look at our Mini or Midi Kilns.
Using native hardwoods, expected output will vary by size, but rough guidelines as well as technical specifications are provided in the table below.
If you’re unsure which size is right for your setup, feel free to get in touch - we’re happy to advise. Full setting up and lighting instructions are provided upon purchase.
