How much storage does your device have? No, not your phone, your biochar kiln! What if you could remove biochar from the bottom of your kiln and keep going? I had the idea of setting my cone kiln on top of a 55 gallon drum and letting the charcoal fall into the drum. I even made some sketches of the idea, but have not gotten around to making one yet. Then I get an email from Larry Peceniak and he has done it. And very nicely too. I really like his idea of welding the cone onto the lid. That makes it super easy to seal. Here's what he says about it:
I had a hole cut in the removable lid of a 55 gallon drum the size of the bottom of the cone kiln. I then had the bottom of the kiln welded to this lid. In the bottom of the kiln I put a piece of 2”x1” fence cut slightly larger than the bottom of the kiln. This holds up the stock to be charred. I put the "kiln lid "on a empty 55 gallon drum, and began to char my orchard prunings from this winter. When the kiln started to get full, I just took a stick and moved the char around and it fell down into the bottom of the 55 gallon drum. When I got tired I just waited for all the stock to char, took the “kiln lid” off, and put a solid lid on the drum to stop the char from going to ash. This was my first burn so I’ll let you know how the char turns out. I think I’m going to try to find a 14” barbecue grate to weld in the bottom of the kiln instead of the fence. However, I was really pleased with the way the kiln performed.
This is very slick and I am going to make one as soon as fire season is over. Can't burn anything right now in Oregon. Here's the picture:
