How it works
Safety note: your BiocharBBQ operates in a unique way, therefore it is very important that you read the operating and safety instructions carefully, as well as watching the associated video.
The picture to the right shows you what is happening inside your stove. As the fire burns back along the stack, the wood left behind is bathed in oxygen-depleted flames, which gasify it through a process called pyrolysis. The gas produced mixes with air as it passes up the chimney, and ignites, to give you a clean flame to cook on. Wood gas is basically smoke that is still hot enough to completely combust. As you push more fuel into the chamber, the charcoal produced collects in the back of the stove, where it cools and stabilises. When you finish your BBQ, you just rake out the combustion chamber into a bucket of water. You then separate the unburnt wood and put it to one side to dry for another time, leaving you with the charcoal; or to be correct, your high quality biochar.
This video demonstrates how to use the biocharBBQ safely, and how to get the most from it!
