The Exeter Charcoal Retort produces very high quality barbecue charcoal or biochar in a fraction of the time taken by a traditional ring kiln. It also cuts harmful emissions by approximately 75%. Contact admin@carboncompost.co.uk

Softwood pallets would offer no more than 80-100kg per burn. Softwood tend to make a very light, hot and fast burning charcoal but it's great for blacksmiths and is also useful as biochar. Any pallets you convert must be made from untreated wood, though. Many wood treatments (especially CCA) survive the process.

The thing is, the answers about what pallet wood has been treated with are more forthcoming than with construction timber. Remember, the pallet might spend six months holding a food product. If you look for the stamp with the ear of wheat logo, if it says "HT" somewhere, sleep easy, it's been heat treated. If it says "MB" on a very old pallet, it's been treated with methyl bromide.

Thanks for info, never knew that!

Most of what you see is water vapour, not syngas. Plus a few non volatiles. This part of the process lasts perhaps an hour, after which all gas from the retort chamber is run through the firebox, destroying greenhouse gases such as methane. Our retort (and most others) reduce emissions by 75% compared to a ring kiln.

This is excellent! I think this is what I've been looking for. - I wish you would get with someone who knows how to use Sketchup and put together some plans for sale.

Why do you keep your temperature below 500 degrees celcius?
@robinrawle59097 жыл бұрын
Because temperatures higher are not good for the steel. You can operate at between 425 deg C and 450 deg C with dry wood. This will slow distortion and erosion right down.
@smh99027 жыл бұрын
Melting and burn through are different. Steel becomes susceptible to accelerated oxidation at 898 F. (Yes I am an American deal with it) and it melts at around 2500 F. So the burn through temperature is much lower than the melting temperature. Repeated heating of steel past 900 F. will cause eventual failure as more of the iron corrodes and then ablates away due to the repeated exposure to high heat and oxygen followed by cooling and contraction.

I think it's because 500c is the optimum efficiency range wherein the source-wood is hot enough to pyrolicize (thus producing wood-gas), AND also within the flash-range for the wood-gas to ignite. The cooler the woodgas, the denser it becomes, the more efficiently it combusts. Keeping the combustion chamber on the low-end of the gas combustion range, results in a more stable combustion. So that's probably it's best 'rate of exchange.' Also, this thing is designed to be in the woods, making coal on location, operating the kiln any higher than it absolutely must be just runs the risk of forest fires. Also i think a 'slow burn' (pyrolyzing at 500* for 4-hours vs 800* for 2) might results in a purer charcoal.

I ( having experience with metal) believe it is in fact that that is an optimum temp for not burning through and ruining your container. Maybe think like this ::::: Take a small piece of metal and try your best to light it a fire. ( won't work, even though most metals are flammable. You say well that can't be, so. Go to the store and buy some non-soaped, steel wool and repeat above directions. What happened??? Well I suppose it caught fire ( well, it should have.) The reason why is ( wait for it). ------------------------------------------------------------------------ OXYGEN. The air could easily get to a whole lot of molecules allowing it to burn. Some of the reason also goes to expansion, due to heat. Which when forced together ( oxygen and steel) the result is rust. Rust is no different than burning ( just in slow motion). So basically, heat the metal hot, expand the metal. The more you heat the more the expansion. The more expansion, the more O2 gets inside the metal. If you google all that I said, you will come to the same conclusion. Thanks all.

"charcoal burning retort"? Think before you speak. You aren't wanting to burn the charcoal. You are wanting to make it. "Charcoal making retort"!

That's an interesting design. Rather a lot of pollution, though. Lot's of greenhouse gases in that smoke. I question the climate impact.
