    Charcoal Charlie looks like a simple and efficient setup with draft management problems. Ithink the most I would do is to increase the clearance around the retort to improve the draft and maybe insulate the fire box to make the heat gneration more efficient to get more charcoal by burning less wood for process fuel. (I might even see if V-belt - another channel- would sling an a occasional load of branch hardwood my way in return for some trade work)

    • @ryelor123
      @ryelor123 6 месяцев назад

      I think a problem with insulating it is that the charcoal might start to burn. The lack of insulation means the rest of the metal is acting as a heat sink when the main fire goes out.

    • @jackmclane1826
      @jackmclane1826 5 месяцев назад

      I agree on the insulation. More heat in the exhaust means more draft. And if the product gets hotter it is also a plus.

    Justin, I've been looking for this update for two years. I love simple solutions for problems....four half inch holes and a length of angle iron! No more creosote. Brilliant! I've been recommending your Charcoal Charlie videos to dozens. There seems to be a lot of interest in making charcoal and especially biochar of late. When it comes to biochar, flame cap kilns or open pit burns seem to be the route to go. You can use a lot of crap wood, there isn't a whole lot of cutting of wood....just throw it in the pit and when you have a layer of coals throw another layer of wood on top. Keep doing this until you fill the pit or run out of wood. Extinguish or snuff out. Not very efficient and constant work during the entire burn.
    When it comes to efficiency, quality and consistency, I don't think you can beat Charlie when it comes to making cooking or forge charcoal. On the rocket stove approach let me relate my experience. Based on a design similar to yours, only instead of a firebox under the retort, I fed an 8" rocket stove exhaust under the retort. Exhaust temps were in excess of 800 degrees F. The retort was an old 300 gallon water tank...in retrospect way too large. After 13 hours of continuous firing the retort leveled off at 140 degrees F. In essence, I built a good wood drier and became an expert on rocket stoves. ( It was gravity fed, fueled by wood chips...ran over two hours unattended.) The lesson learned is you need a BIG flame under the retort. If you should go this route, calculate the BTU's you need for your size retort first. I'm converting my creation to a Charlie this spring.
    I agree with your comment on the baffles disrupting the air flow around the retort...don't think they are necessary and probably create a little more smoke until you are outgassing.
    Thanks for doing the update. You've got a lot of interest because it's a well thought out project that works! I've seen a couple of videos similar to your design, but not as well functioning. Best of luck in your continued adventures, O.J. in Oregon

      One big benefit of flame cap kilns is that you achieve a higher temperature and thus higher quality biochar if that's what you are after.
      For forging however char from a retort like this is more ideal because not only is it dry from the start but due to having been cooked ad a lower temperature the energy density that remains is higher.

    One thing that comes to mind is that you are probably loosing at least half of the wood gases out the chimney, simply because the gases from the two holes closest to the door consume all the oxygen before it reaches far enough back the firebox for the second and third holes.
    It might be better to either just have the two first holes, counting from the door, or you could put some sort of air intake, possibly just open the old gas pipe, at the back to get air to those gases before they go out the chimney.

    A thermometer?
    That was smart.
    The people into biochar are talking about the burn temperature so that thermometer should lead to a better quality I'd the necessary controls are in place
    If the holes were not at the bottom I am thinking one can then meter the gas to have the pyrolysis happening at a relatively constant temperature.
    Also by controlling the rate of burn it is possible to save some of the excess gas for subsequent burns, reducing the need for fuel wood.

    • @GunBed

    Is fire at the bottom starved and oxygen + smoke getting pulled straight down the middle for a reburn

    • @JustinJennings

      I'm not sure there's a simple way to make any fire smokeless. Injecting oxygen into a heated stream of unburned hydrocarbons will allow them the opportunity to burn off. The fire box is having flow issues. The gasses from the pyrolysis are being injected into the fire box as a fuel source. I hope I understand your questions and I hope I answered them.

    I don’t believe I see a grate under the fire in your fire box. Without a grate, your just burning from the top. Get some air under that fire. Maybe a draft vent under the fire, and an ash receptacle. If you have a grate, it must be filling up underneath with ash, blocking air flow. (Although, that is a lot of metal to heat up before a good draft can develop.)
    It sure does make fine charcoal. The only thing that concerns me is how smoky it is while starting up. Have you ever made a load of charcoal using charcoal in the fire box? It would nearly eliminate smoke. (It would make an interesting video👍)
    Thanks a lot for sharing this. I was thinking about using the external pipe. What you’ve done looks good and it helped me understand some other configurations I’ve seen.

      Using charcoal to make charcoal uses up the product you want. I used to live in a city that had a street lighting system that was powered by gas made from making charcoal in retorts similar to this. The retorts were cast iron with a pipe exiting one end while the other end was full diameter for sealing similar to charcoal charlie. The retorts were mounted over an oven of brick. The exit pipe went to a tank with a cast iron can with the open end down so the gas bubbled up through the water and was caught in the can. The water cooled the gas and kept the gas in the can under pressure. Pine knots and other parts of the trees not used for sawn lumber were packed into the retorts. The retorts were sealed. The charcoal made from the previous day as well as any additional fuel was used to heat the retorts. The street lamps were connected to the gas supply and in the evening, the lamps were lit using the gas. When the charcoal-making process was finished, the retorts were allowed to cool some then opened and the charcoal was pulled out and new wood packed in to repeat the process. There are a number of those retorts still around town because they cracked after being used many times for firing. The town is Jefferson, TX, and was the first town in Texas to have street lighting in the 1800s. Of course, the object was the gas. One of the tank pits is still there.

    No worries about gas pressure or explosions due to clamping it off?

    • @JustinJennings
      @JustinJennings  3 года назад

      I'm not worried. There's a T on the back of the upper chamber from how it was originally plumbed. I could open the top of that T and set a ball bearing or a piece of plate as a pressure relief. But, it seems unlikely that material could block those holes venting to the fire box.

    Hello,
    I have some questions about Charlie
    How does it look when it comes to conversion rate? From what I know the yields can vary from a fifth to a third of what's pyrolysed, depending on the speed and temperature of the process, and I wonder how Charlie fits into that
    Also, would some kind of insulation of the fire chamber help in lowering the amount of fuel needed?

      If I remember correctly, the full cycle is about 4 hours. But, it takes a while for everything to cool down to empty it. The last couple of burns have been in the evening, and I just empty it the next morning.

    What if you were to use the forge the same time your making charcoal. Kill 2 birds with one stone so to speak? Or use the bottom as a forge when the gases are burning for the extra heat? A rack to set your metal on close to the gases.

    So ... a question: the 1/2" holes that feed wood gas to the firebox to improve the burn don't appear to be able to be blocked when the burn is complete so how do you keep oxygen rom going back into the retort and causing the charcoal to burn up?

    • @aclass9290
      @aclass9290 3 года назад

      Oxygen going into the firebox wont have the chance to go into the retort from these tiny 1/2" holes before being burned, and if we assume that oxygen did enter inside the retort its really hard to ignite.

    • @AuraTrimCoMeath
      @AuraTrimCoMeath 3 года назад +1

      Kiln does not have a chimney, so even oxygen could entry, the burning would not take a place due to lack of exchanging gasses.

    • @JustinJennings
      @JustinJennings  2 года назад

      That usually means the reaction is complete because there is no more wood gas to generate. But, I'd toss in some more fire wood if I though it needed more time to convert.

    After drilling those holes and seeing how much better it works, I realize how unnecessary all this work is to build such a stove. I take a 35g drum full of wood with holes in the lid, stick it upside down in a 55g drum, and have a fire around it(around the 35, inside the 55). Same results. Works perfect every time.

      One huge potential benefit with a more advanced retort is the potential to extract wood vinegar, py-oil and run the remaining gas into an engine.
