I brought the same stove and it is amazing. After the fire is out the stove keeps on giving immense heat for about the next 30 minutes. Its very amazing i love it.
You've explained how some people think they work, but I'm not convinced. They think fuel is coming out of the upper jets because they see flames coming out them. What I think is happening is that air comes in the bottom and some goes under the wood and burns it, but without enough oxygen. So above the fire there is heat smoke and wood gas rising. Some of the air that goes in the bottom goes up the hollow side walls and heats without losing any oxygen. At the upper vents you then get hot oxygen injecting into hot wood gas, so you get flames. That's my theory because I don't know why hot wood gas would go down, or why it would wait until it gets to the jets to burn if it did, since it would have hit oxygen in the base. Edit: And now i read Hannes comment below and looks like I may be right!
FlashGeiger that's a great point and makes complete sense. I'm no expert nor have professed to be. I purely tested a couple of materials and explained what I experienced. I have a small amount of experience with wood burning stoves, household stoves. My goal every time I lit one of those was to get to the point where I could see the gasses from the wood igniting above the bed of embers. A beautiful sight. Similar to to the aurora borealis (sp?). I was told it was also known as the 'dragon's breath'. My understanding of that event was that oxygen hit a very hot and flammable gas from the wood which would ignite and create the cloud like rolling flames. Passing this on to the gasifier stove I'd say the exact same thing happens but with slightly more virocity as the 'oxygen' is pre heated and forced through small holes as opposed to simply being leaked through vents above the glass door of a household stove. Is it the gas from the wood that is drawn down then up through the cavity in the stove, or is it just simply oxygen drawn from the outside of the stove? I'd speculate it's both. But I really don't know. Either way this system is very interesting and certainly something that needs exploring more. Thanks for you comment flashgeiger and thank you for taking the time to watch my video.
Yes there is no fuel gases flowing through top holes, only preheated air which is high enough in temperature to enable secondary burn of otherwise unburnt gases.
I have this same stove minus the little pan for gel fuel. Its great, isn't it? I liked the way you filled the chamber with wood and then lit it from the top. That's the correct way to do it. Of course, that Meth fuel helped get it going! And those wood pellets sure make a nice flame pattern! I was amazed that I saw hardly any soot on the top of the stove as it burned. Great demo, thanks.
Hot air doesn't go down. The gasses are not drawn down and come up the outside. Air is drawn into the bottom holes in the base and come up between the double wall as hot air and reignites the wood gas left over from the primary burn on the inside chamber.
Nice comparison between wood pellets and sticks. I have one with the rounded top. I do prefer the one like your, but I bought it for 10 US dollars... I thought I was having problems in mine, because people on TH-cam have a much better fire. But now, I think it's just that wood pellets work better. Thanks for sharing.
I think the flat flakes of wood might slow the downwards flow of gas a bit, as they all sit flat on top of each other. Maybe knobbly lumps or short twigs would work a bit quicker?
@@bradwilkinson6974 if you lean the stove over on its side when loading the flake wood fuel and load it so the chips stand in a vertical orientation it will greatly improve air flow through the fuel load. As always wet or damp fuel will smoke.
This guy is awesome! No idea Liam Neison was doing stealth stove reviews on TH-cam! " I'd pay good money to hear him say, " this stove has a very special set of skills..." Outstanding mate!
All with best intentions and appreciation. I've been building/using these stoves before they were 'cool' and yours is one of the better tutorials on TH-cam. Best, N
A great video Brad of a fantastic stove and good to see someone loading stove then top lighting as this is how it should be done rather than bottom lit and fuel added. Peops give up on this stove due to this. Really enjoy your channel and have subscribed. Happy wandering. Paul :)
Ha ha! That was just my luck. I was using a galaxy s7, I think. Then it was too dark to see anything, then I was interrupted. It's just how it goes. Thankfully I just did the video for fun and not to try to impress anyone.
A very nice video showing the right TLUD method. Too many people don't light those woodgas stove from the top. Regarding the gasification or pyrolysis the stove as to reach arround 500C to properly work and start to show the jets. Usually after the starting material as burned you will see a white smoke coming out and after it's go et be ok. Take a look to my Channel I have started to put some vids of the one I have made myself. Sorry if it's in french but you'll get the idea. Ciao from Quebec
I would not burn indoors, it is not a safe thing to do anytime. One exception would be if you have a fireplace then you could burn inside the firebox area.
It looks really good Brad, I love how these stoves work. The top on this stove looks better than some of the more well known ones. I am waiting for the post man to deliver a new bush box stove which I am looking forward to trying. I look forward to seeing you using yours in the woods. atb Mark
I know people talk about putting in more pellets but I'm telling you sometimes less is more only fill out the bottom drop insert pan and do not feel it 3/4 the way up or more there needs to be a oxygen barrier gapping if you overfill it you're hindering its ability to work
yes it would definitely be able to cook pasta for several people. it's a very sturdy design and would easily withstand a large heavy pot. You'll most likely need to keep 'feeding' it but, to be honest, that's something I really enjoy about the stove. Obviously you'll need to take care balancing a large pot and make sure you sit the stove on sturdy ground. pasta for 4 or 5 people will take quite a bit of water which will be heavy and potentially messy if the pot goes over. Thanks for watching the video!
TLUD stoves are batch load stoves. You lode them with fuel light them and then leave them til they burn out you don not add fuel as they are burning as this will interfere with the pyrolitic process. Question for you, when you use your stove does any soot deposit on the bottom of your pan? You should not use meths or other solvents to start wood in this type of stove especially when using wood pellets. Reason is the pellets are very dry and the meths will soak in making the pellets expand which blocks off air flow through the pellets. A really good way to start pellets or wood sticks is with one or two cotton balls soaked with Vaseline. Tease out the cotton balls and spread them over the top of the fuel load and light. Valseline soaked cotton balls will fight under any conditions and best of all no smoke will be generated.
Moray I'm so sorry I missed your comments when you made them. That is fantastic and sound advice. I will most certainly try vas balls next time I use the stove. I haven't noticed any soot forming as such. There is the remnants of the pellets or wood left but it's often in a charcoal looking form or ash. Thanks for sharing this and sorry again that I missed your comment.
@@bradwilkinson6974 I have found that cotton make-up pads are also effective and are much easier to use. Because the pads are stable you can apply the Vaseline to them much easier than cotton balls and with far less mess that results with cotton balls and the pads stay flat and maintain their size/shape while cotton balls want to clump up. Hope this is of interest.
@@morayjames92 yet another great tip! Thank you. Cotton balls are a pain to load up and it gets everywhere. I like your thinking. Thanks for sharing this. (sorry I replied from the wrong account a moment ago).
David Beasley about 12 minutes in I change to the wood pellets, which is the cat litter. Not all cat litter is made from wood pellets, so it's probably worth checking before you try burning some of the crystal looking stuff! Could be illegal!
If you want it to gasify properly you have to stack your sticks in vertically so that the gas (smoke) can make it's way down and through the diamond-shaped holes in the bottom and back up through the double wall and be ignited. Placing wide flat pieces of wood like you did blocked off the holes in the bottom and obstructed the air flow...
that was wrong explain. The gas produced from the combustion rises and ignites when mixed with the oxygen that goes in through the secondary chamber. I do not know if I explained myself well because I do not speak English very well! Anyway, nice video!
Santiago Granada thanks. As I pointed out in the video, I'm not an expert on this system and in other comments we've discussed other theories on what happens during the burning/combustion process. There is a draw down through the material. Would this not possibly contain wood gas too? Never the less, it's a clever system and very interesting to explore. Thanks for your comment Santiago! All the best to you.
Hi I'm afraid I haven't got the stove to hand as I'm away with my family on holiday bit if you can bare with me a couple of days I'll assemble the stove and measure the smallest pot size for you. Please message this video again if you haven't heard back by Monday. All the best. Brad
I got a big bag in Tesco so pack a smallish amount to get the first burn (enough to make a brew) when I set up my tarp, the set twigs and pine cones from the forest floor between the stove and a windshield to dry out a bit before adding them to heat my scran
Haha! You're welcome. There are enough videos of boiling water. We know it'll boil water! Doesn't matter if it's 4 minutes or 2.572 minutes. Thanks for watching and commenting. All the best to you.
There is no down draft of the wood gas. Common myth. Hot air rises. What you get is a secondary burn of the gasses as pre-heated fresh air comes out the jets.
Hi Ron. It was a bit of an experiment and a learning experience at the time. Quite a few people have put me right since then haha. I should have read up a bit more about the process at the time, but I really enjoyed trying it out. All the best Ron and thanks for watching.
@@bradwilkinson6974 no worries. The top load down draft idea spread wildly during the early days of double wall stoves. The engineer in me has long been on a crusade to correct that.
Can't find the seller I bought mine from but here's a similar one for the same sort of price: www.amazon.co.uk/gp/aw/d/B00VHF20W8/ref=mp_s_a_1_9?qid=1463122082&sr=8-9&pi=AC_SX236_SY340_FMwebp_QL65&keywords=Wood+stove+camping
Also, this is a WOOD gas stove. It's not really made for fuel gels or alcohol fuels. Therefore, that little plate is made for ashes and coals that fall through the burn chamber. Look at Silverfire's Scout stove, from which this one was copied. It has a permanently attached plate under the burn chamber for just this purpose.
Bad advice that you gave. Never use one of these stove indoors or in a enclosed space. Even though there is no smoke it will still give off deadly carbon monoxide. I spent 20 years in the fire service and went on several carbon monoxide calls from people trying to use charcoal grills inside, they thought the same..no smoke, no problem. Other than that good video.
You're absolutely right and if I could remove that comment from the video I would. I did mention carbon monoxide detectors in the video, however that's not good enough really. I do hope no one actually does try using one of these indoors. Thank you for your comment and I'm pleased you enjoyed the rest of the video.
@@mitchpanek7121 CO2 is not a hazzard and burning gas produces no where near the amount of CO as wood. Otherwise people couldn't have natural and propane kitchen stoves.
The person who designed this stove did not understand the gas flow dynamics of a woodgas stove. When a woodgas stove is made with the correct gasflow within 2 minutes of ignition a blue flame is created and it stays blue until a short time before the fuel is completely burnt. Blue flame produces no soot and the fuel is burnt so efficiently there is no need to add any more if it has been packed in properly at the start. A woodgas stove using a baked bean tin combustion chamber correctly designed and properly packed will burn a blue flame for well over an hour.
Thanks for your input umvhu. I'd be interested to see a video of the stove you're talking about if you have a link? Just so you know, I'd never used one before this video and the purpose of the video was to explore how it performed with different types of wood and also to try and learn myself, what was going on with the system.
