Tim,
The primary air holes would be the ones in the bottom of the bucket. The secondary air holes would be located in the reducer that goes between the lid and the chimney.

Thank you that is what I thought but wanted to make sure hopefully I will have my own TLUD tomorow

Your welcome! I'm glad it helped, and happy you have a tlud now. It's a fun, easy way to make charcoal.

With pro's like Lloyd on their side I should be all over these, but I just don't see why this should be a good method. As far as I can tell the heat is simply radiated down from the top, so in order to cook the entire fuel load the fire needs to propagate through most of the cooked charcoal. Or am I missing something? 

 

Also the wood is exposed to fresh oxygen during the entire process, this is about as far from the retort process you can get.

I have used both retort and TLUD methods, and charcoal from both works well. Each has its own advantages and disadvantages, and a fireworker may decide to use only one, the other, or both.

 

With TLUD, it is not that 'heat' is radiated down, as you think of heat in the retort sense. It is literally a layer of fire in the container that moves from top to bottom. This fire has a couple of critical effects different from retort method: 1) some of the bio matter is actually burned and does not become charcoal, meaning a lower rate of uncooked to cooked (less efficient), and 2) no external heat source is need, so there is no constant refuelling like a retort and different types of wood are not needed (who burns willow to heat a retort?).

 

So, if someone already has a retort setup, already has a good supply of both fuel and charcoal wood, and has the time to wait for a retort to complete while potentially constantly refuelling it, a TLUD might not make sense to use. But for others, the speed (and it is really really fast) compared to a retort as well as the lack of need to build a full fire pit or containment system make a TLUD system super easy to setup, run, and store away.

 

EDIT: My anecdote: Setting up my paint can TLUD, running it to completion, and setting it aside to cool takes less time than it takes just go from zero to having a fire in my fire pit big enough to set my retort can in.

I know I've sworn not to chase perfection for the sake of perfection, but the TLUD barely seems better than picking charcoal out of a fire pit. It wouldn't bee so bad if it at least tried to channel the heat back, but the charcoal seems more like a coincidental byproduct. I've been trying to redesign it to some sort of retort hybrid, but I haven't had much success yet. 

 

 

Separate fire wood isn't a problem, I already have that for heating purposes. And to be honest, heating a retort using the good wood isn't any worse than what the TLUD is doing. In theory a well designed retort should waste less fuel than a TLUD.

If it channelled the heat back, you would have wood and charcoal blowing all over the place. The thing really sounds like a jet engine because the 'exhaust' heat is moving so fast when it leaves the chimney.

 

Maybe separate firewood is fine for you, but there are others who do not heat their homes with wood and do not have a particularly heavy supply of cheap wood.

 

I do not know what you mean by 'isnt any worse than what the TLUD is doing'... the TLUD burns instead of converting a small percent of the input, running a hot enough external fire for long enough burns a lot more than the TLUD does.

 

I am still not sure why you are so concerned about convincing other people not to use a TLUD. Just because it is not the best option for you does not mean it is not the best option for everyone else. As I mentioned above, there are real reasons a person might choose either method over the other, you clearly fall in the retort camp. (for the record, I use both methods depending on the input material, time available, and if I am already having friends over for a bon fire).

I'm not. I just don't "get" them. In fact they frustrate me a bit. They do seem very convenient in use, I just can't bring myself to trust the result. And I still think it should be possible to make a more efficient hybrid TLUD/retort cooker.

There might be a more efficient hybrid, and if you come up with it, I am sure there are many here that would love to test it. If you want to create a hybrid, I suggest running a regular TLUD a few times to get a feel for how they actually work as just reading, seeing pics, and watching vids does not get across the power of the exhaust you want to capture.

 

As for the results, I have used both methods and the charcoal comes out just fine with both, including the TLUD.

I don't know if I've ever seen a good side by side test. I'd be interested in seeing some real results like that.
Just so you guys quit asking, here is the link to the old forum. http://www.xsorbit2....forum/index.cgi

Me too. I'm just not sure if I want to make a TLUD for that purpose alone.

If I get a chance this summer, I may try recording both and posting them.
