I would suggest wrapping your retort with Kaowool or Rockwool, to start, you need to keep the charcoal feedstock above 451° to gassify.
That is a simple and effective step, i look Forward to seeing what happens next.
I have a design kicking around in my noodle where you build a rocket stove, using a 15 gallon barrel for the heat bell, that being welded into a removable lid 55 gallon drum that is wrapped in insulation, then venting the exhaust up a secondary stack with a vent line from the charcoal chamber to the intake of the combustion chamber.
Also is your burn tunnel insulated? Are you losing heat and energy to the sides and floor of the burn tunnel?
Awesome, thanks for the suggestions. I look forward to your Idea coming to fruition. I will subscribe to your channel so I won't miss it. Also insulating the retort oven and the burn chamber is a great and simple to implement idea. thanks for watching.
No, I am loosing a lot of energy in both places. Thanks for the tip.
Interesting build. I have been looking at doing something similar.
If I were given this project to modify I would do the following:
Make the basket full size. This gives you the option of using things other than pellets as well as gives you as much fuel as you need to achieve your heat goals.
Intake air from the front with air control (at least until you figure out what size works best then you can remove the extra weight/moving parts).
Add pipes in the bottom going from the front to the secondary burn area with ability to close them off, you only need them open when it is hot enough to have secondary burn.
Insulate insulate insulate.
Add a fan to the mix for getting up to pyrolysis temperature. I read that you want to keep it portable. I think a 12V tool battery would last long enough on a 12V blower type fan to get it up to temperature several times.
Good Luck
Great suggestions 3Hose, you're hitting on all the good points. You're the second person mentioning adding a fan, so I just might try that. Thanks for watching.
Very cool!
Thanks, much appreciated.
You could also pipe the wood gases into the burn chamber to produce more heat
Great Idea, thanks for watching.
I have watched several videos like this with similar results. they then insulate the burn chamber with something like a ceramic blanket or a product that will withstand very high temperatures, then put a metal wrap around to keep it all together, and they get a good result.
May that is worth trying
Yes, your the 4th person to sugest that so I'm going to try that. Thanks for watching.
Really cool project
Great, thanks for watching!
Just put a baffle in the exhaust pipe to keep more of the flame in the pipe and that will heat it up more and as to get a longer burn make the feed smaller and taller as it will act as a blast furnace
Very good suggestion! Thanks for watching and I think I will try this. Now, I need a little more info on the " make the feed smaller and taller as it will act as a blast furnace" part.
A longer chimney. It'll cause more up draft to help air circulation to help burn the fuel being fed in
Very good idea, I'm been looking for that steel chimney pipe instead of that cheap aluminum stuff but haven found any. I need to hit Ace Hardware, they have everything. Thanks for watching.
And put some metal or rebar to create a hot spot before the flames enter the up pipe
This sounds interesting, but I do not fully understanding the concept. Retaining heat is a good idea, but a rebar in the burn chamber will make the bun chamber hotter., correct? I need the "up pipe" hotter. Thanks for watching and for the suggestion.
I. Thinking to get the wood to charcoal all the way is to have it rotate so all the wood get even heat as for the rear yes it will make it hotter but that's to ensure all the pellets you are using gets all the energy out of it for more efficiency. The tube you put the pellets in make it taller to hold more with a lid to control the air flow but make sure its fits the burn box tightly
Close off the part your fire cage is in and only allow the air to inter from it with a lid to control the air flow
Hmm, you got me thinking about how much air I have flowing in from places I don't want it to, like the pellet feed area. Good idea, thanks for watching.
Add a small blower fan
Now this is a thought. I would need to make the fan solar powered as I want to keep this portable and small. Thanks for watching.
You can use a blow dryer or a fan from a computer bolted to the end of some pipe so it doesn't melt. I think a blower might increase the conversation rate for charcoal from increased heat.
@ministermanoutdoors6179 it would probably take less time with a blower.
I don't think you need a larger wooden pellet basket.
Maybe it should even be smaller when the entire unit is rebuilt and insulated.
When insulating the rocket, do not use Rockwool, as Rockwool cannot withstand the temperatures that the combustion box and riser can reach.
Instead use Ceramic Fiber Mat Insulation which can withstand temperatures up to 1200 degrees celsius (= 2192 degrees Farenheit).
And do not use metal for the combustion chamber and the lower part of the riser. Use insulating ceramic stones instead / or Vermiculite plate (Listen to Loz Harrop, who tells You about what you should expect, including limitations, when You use them).
It would be desirable to lead the gases from the pyrolysis container down, via a pipe, into the combustion chamber or the lower part of the riser.
How this is best done, I currently do not have any good advice.
The only thing I would like to mention is that the pipe with the gases from the pyrolysis container should be terminated so that you can see this from the outside while there is still fire in the combustion chamber, so that you can assess when the pyrolysis process is over.
This reveals a need for a refractory glass at the end (the beginning) of the combustion chamber. So why not place a small hatch with glass and air damper at the end of the combustion chamber.
And then a lid is added over the pellet hopper so that the air supply can be controlled.
You do not need a fan - If you do not have enough draft in the Rocket, add length (height) to the chimney and keep the chimney isolated.
Insulate all parts including the pyrolysis container

Temperature Measurement:
During development of this charcoal production unit, it may be desirable to be able to measure temperatures in different places of "the rocket".
For this purpose I imagine that type K temperature sensors will be most suitable, as they (some of them) can be used for temperatures up to 1100 degrees Celsius (= 2012 degrees Farenheit).
The reason I mention this about temperature measurement is that it can be a method to determine at what height the pyrolysis container should be placed in the riser.
The pyrolysis container must not be placed too low in the riser, as it then becomes too hot, which breaks down the metal tube too quickly, but also not too high, as the contents do not become carbonized.
The Temperature Mesurement can be seen as en separate project. It can be made by using an Arduino connected to one or more MAX6675 Thermocouplers. It can be used to measure temperature in the range of 0°C to 1024°C
For some years I have been making charcoal for biochar in a pot in my wood-burning stove (boiler), and at one point of time the stainless pot lost its bottom. The bottom contained an aluminum plate, which melted.
Aluminum has a melting point of 660 degrees Celsius, so we know that we can easily reach this temperature level and higher in the burn chamber and in the riser.
And this is the reason why we should not use metal for the burnchamber and the lower part of the riser.
According to Loz Harrop, this is the bottom approx. 30 centimeters of the riser, which should be considered a part that needs to be regularly replaced due to temperature degradation, and therefore should be an independent module.
Wow user-ul9vy6xj3d, where do I start! First, thanks for watching, and second, thanks for all the great ideas. I realize at some point the burn chamber and heat riser will need replacing, so considering fire brick or something similar is a great idea. I still want to make this unit portable.
The Arduino Temp monitoring system is yet another great idea. I was wondering how I could monitor the temps at different locations in the unit. I know just the guy to program that unit and he's an electrical engineer, a buddy I worked with in the past at another firm.
I'll check out the Loz Harrop channel as well.
Thanks for watching.
Ah yes, I've seen his video before (Loz Harrop). His rocket heater is very similar to the guy's design over at the Zero Labs Channel.
Four wheels will make it movable, and a brake or bricking it up will stop it from moving ;-) @@ministermanoutdoors6179
You don't want any air getting in but what's coming in from the feed tube
Okay thanks, I will see if I have air leaks and patch them. Thanks for watching.
