Recently bought a Woodgas Stove for around about £35. The principle is that it has a double wall with holes on the outside cylinder at the bottom, and holes on the inside cylinder at the top. The inner cylinder is filled with twigs, branches etc. or in this case wood pellets (cat litter! - availble at tesco at about £3 for a 10 litre bag). Once filled, the material can be ignited from the top. After about a minute gases from the primary burn of the wood, mix with air that is drawn in from the outside and ignite. the result is several jets of woodgas mixing with air coming from the holes at the top of the inside cylinder. Once this secondary ignition takes place, the burn is smokeless. Some pictures of the stove;

just tried a burn using wood pellets; Initially you get a normal flame; but then the woodgas starts to burn;

If you click on the photos you can clearly see the jets of gas burning. It burned fiercely for about an hour on a couple of handfuls of pellets. At the end of this it left charcoal which smouldered for a further half hour.
Excellent little stove! 10/10

Just been out to empty it now it has cooled down. There is a very thin layer of white ash in the bottom of the burner, and that is all that is left. Next time Splitty comes down to mine, I will try it inside his woodburner to see if it heats it up well enough, it should do and would be a great way to heat the van for an hour and a half on a couple of handfulls of pellets. Somebody has tried this; www.youtube.com/watch?v=zVY4aiFhkuM

You can indeed Chris, I did this when it got down to charcoal, it still works the same, but I believe when you burn from the top downwards it burns for longer if that makes sense.

Might get rid of a few now though, although my sons use them for night fishing as well so they might object. This latest one is the only stove I am taking to Scotland with me next month.

my mate used to run an Austin lorry on a woodgas converter he´d built on the back.he was a scrappy and water heaters used cork pellets for insulation so ha had tons of it,said it was the best fuel altogether. so get all the corks from the local restaurants,stuff your canoe full of them !you´ll never sink.
for them as don´t know, a lot of motors ran off this gas,especially during the last war,usually filling a large gasbag on the roof,but some had a small converter-producer on a trailer

(Might have been posted on WC4MH). I will try corks. We seem to be accumulating a few at the moment.

Nice vid Rob, I have seen a couple but this one was really clear. Itching to make one now. And cat litter pellets a good tip - the bags I have bought of that stuff, but never thought of it as cooking fuel - very economical use if not in a woodland area

gave it a try inside our woodburner at home today. It took a while to get the top plate hot as it is quite a thick plate, once there though, we got a nice bit of warmth out of the woodburner for about an hour on a couple of handfulls of woodpellets. I would imagine in a smaller woodburner inside a van or tent, it would have made it very warm! Started up and ready to go; Doors closed once woodgas started to burn; In full flow and producing a fair amount of heat;

Thanks for the review robmac. I've just ordered one of these on the strength of it, I hope it's the right one That's the one. If you get the Tesco's cat litter wooden pellets, fill it up (I plan to get some mesh to cover the holes in the base as these pellets can drop through them), light it from the top so it bursns from top to bottom, once the material lights, the woodgas jets will start up after about a minute. Alternatively you can just use twigs etc.

I've ordered it to replace the Trangia in my INCH (I'm Never Coming Home) bag. The Trangia is a really good stove but carrying a litre bottle of meths is really a bit heavy. And of course it wouldn't last forever. With the woodgas stove I'll be able to pick up an unlimited supply of fuel to burn wherever I am. I bought the woodgas burner because it can stay in for such a long time with woodpellets. For tarp camping when I carry everything I need on my back, I take my Honeystove, another nice little burner which can run on twigs or Pinecones etc. Plus it can fit in my jacket pocket! Very useful in places like Scotland, where it is frowned upon to have an open campfire in the forests.

The Honeystove looks good, especially as it takes up so little room. There's a couple of things I'm hoping will work with the woodgas stove. First it will be good if it fits inside my current pot set. Secondly I'm hoping it will work with solid fuel. Not for any length of time , just so I can pack a couple of blocks inside in case first day out there's no dry wood about. No great deal if it doesn't work with them though. Shouldn't be a problem. I've tried mine with some quite thick blocks of Pine and it's burned really hot without warping. When packed down, the stove has a diameter of 13 cm and a height of 7 cm.

Thanks for the post Rob - I've ordered one of these, now reduced to £30. Interested to try the pellets too. Will a covering of the base burn enough for a small kettle (2 or 3 mugs worth)? A new toy!

I am sure it would, but if I were just doing a small kettle, I would just throw in a few twigs and top up if necessary. Free fuel is always good! Just one thing, I stand mine on a bit of tin foil, just to catch any of the fine ash which drops through the bottom.

Nice thread!
One of the things I use is a primitive, home-made version of this. Basic principle is the same.
Talking about wet wood, I have to say that almost eveything in my set-up is soaking! That said, I do believe I can see the sun-shining!

Ps I've got one of those cartridge cookers stashed away in the van for when I run out of gas! Used it in France to cook outside too.

I've not done it for a while, but a mate of mine who I go walking with is planning a local trip as we speak. Bear - Noooooooooo. Mans an idiot who hangs off cliffs clinging to a vine! And as for eating insects, I'm more of a steak or smoked Salmon type of bloke.
