Hi Kevin! Greatly appreciated the upgrading in the retort with the incorporation of the galvanised iron (GI) pipes in your design,which i assume helped in bringing the efficiency of the system to much more than 50%. I still have two querries: I) how does the inner drum/trash can rest at the bottom of the bigger outer drum with the tee-piece and GI pipes welded underneath? 2) don't you have to fill the space between the two drums with woodchips to "ignite" the fire? Thanking you in advance for a prompt response, warmest regards from Mauritius!
@Volintena7 ай бұрын
I) 0:46 - 0:48 You can see the iron bar or profile on which the inner drum/garbage bin stands. 2) When a fire is lit, it heats the inner drum/garbage bin and as a result of the heating of the wood in it, flammable gases are created that escape through the small holes and become a fire, thus the inner drum/garbage bin ignites/heats itself and no need to add additional wood to burn. Kind regards from Sibenik, Croatia, Europe!

You could drill holes through the rim of the lid and upper rim of the barrel and thread the long stem of a "J"-shaped piece of rod through.
@glennmartin64923 жыл бұрын
If you drill through the lid and barrel downward at an angle you could probably just use long bolts. The weight of the shaft will keep it in position. The head will keep it from falling through the hole and it will probably be easier to inert when the can is in the barrel.

Great build Kevin other than the gal can, but you know about that now. Just wanted to clarify after the gas off pipe turns the elbows and comes up the side of the can does it go back into the can at the top or just terminate with end caps? I hope that makes sense to you. Just wanted to know if it gets circulation happening or just relies on the holes in the pipe to reduce the pressure. Great job anyway, Look forward to the upgrade video.

It appears to me that he used a length of pipe that is open ended on the top in the center of the trashcan (mounted vertically). On the bottom of that length of pipe he used a threaded coupler, 2" long pipe nipple, and then a tee (the purpose of the nipple is to hold the vertical pipe inside the trash can). Then he used whatever length of pipes needed to get from the center of the tee to the outside edge of the trash can plus ¹/² the o.d. of the pipe, screwed on a 90 degree ell to those lengths of pipe, then ran lengths of pipe up the sides with 90 degree ells screwed to them. Im guessing that he also used 2" long nipples and couplers threaded into the 90's through the sides to also retrieve wood gas, as well as provide more support for the piping. He then drilled holes in the pipe on the bottom of the trash can to allow the wood gas to depressure thus also providing fuel to the fire under the can. Not sure what size the holes drilled in the pipe were, but maybe just a tad bigger would help with the lid situation.

Designs like that can work but you will get a lower yield of charcoal at the finish. I use the pipes to keep oxygen from entering the inner can. The way to tell if air is getting in is you’ll have ash.

@kevincarnahan98595 жыл бұрын
yveskc1 the way I did it I haven’t had any ash in the retort chamber which would let me know if there was any burn. I did have to use wood stove gasket and wire to seal the lid due to the gas pressure generated. I’ve done 5 burns with the same results. I did drill out the outer holes at the bottom to increase air to the fire and has cut down the overall time to 4-5 hours and cut the wood consumption in half. I still have to use the door to fine tune the air once the gas starts to burn off. Once the gas starts to burn well the whole drum glows red and still have to feed the fire under.
@kevincarnahan98595 жыл бұрын

I used threaded pipe with a T fitting, two more threaded pipes to elbow fittings. Above the T fitting is a 2in threaded connector to a straight threaded connector. That way I could connect the longer section of threaded pipe. Had to cut the pipe inside the can because it was taller than the inside height of the can. Ended up having to wire the lid shut from the pressure created from wood gas. Also had to open up the air holes around the outside can to get a cleaner burn.

The dryer the faster it will carbonize. I use wood that is between 4-6 months time drying. I use old pallet wood to fire it. Usually takes about 2/3 of a 30 gal trash can with pieces no longer than 9 inches. Just be sure to keep the fire hot because it will keep the run time of the process to about 3-4 hrs. Once you stop getting the wood gas burning out of the pipes your done. I usually start about sun down(around 6pm )and it’s done around 9-10pm depending on temp and wind. I have better luck on calmer days with the consumption of scrap wood. Be sure to secure the top on the inner can. I used heavy wire from the handles to secure the top down. May want to wire the pipes to the can as well. With the high heat they get loose. Everything is good to go by the next morning. Make sure the can is cold to the touch so you don’t get any flash ignition of your newly made charcoal. Good luck and let me know how yours turn out. I’m probably going to upgrade the inner can to a unlined 20 gal drum with lid. Don’t think the trash can is going to hold up for that many burns. I’ve done 4 runs so far and made about 40 gal of charcoal

The smaller the diameter the pieces the faster it will convert. I use little sticks broken up to about 2-3" in length and none bigger around than my finger.
