As a side step, I've been busy the past couple of weeks with gathering materials and making a scaled-down version of the institutional barrel stove. It's an absolute delight to cook a meal on this one, it's fast and reliable. It looks like this.  The whole thing is built around a 10 liter pot (2.64 gal) inside a 15 US gallon barrel. It's capable of bringing to a rolling boil a quantity of water half the size of the pot, in around 25 minutes with a mere 14 ounces of fine split dry wood. Smoke disappeared completely 5 to 10 minutes after lighting it. More pics of the build at Picasa:And of course, the Testo gas analyzer had to have a sniff at it. The results are partly excellent and partly less. The burn was very stable after the initial warm-up, with a nice quite low CO level. The oxygen level did stay on the high side, so the efficiency was kept a bit low. Despite the low end temp, hovering around 100 C, which correspond with 210 F.  The temperature at the outside of the barrel wasn't high enough to discolor the paint, and the chimney pipe could be lightly touched without repercussions. The cook who'd ask for this particular stove is very, very pleased with it. (Her own words) |

where is the ash clean out? There's none. It's frugal on fuel, very little ash is produced. In practise, every time before starting up the cook will clean the innards with a very small brush. |

What are the dimensions of that barrel and where did you get it?

What are the dimensions of that barrel and where did you get it? The dimensions, from the top of my head, are: 15.9 U.S. liquid gallons, 15" diameter, 23" height. It is built as a pail, slightly conical and with a removable lid. I've bought it from a cask trading company in the Netherlands. I am willing to give you the address, but I don't see the relevance. Here it is: Goedhart Vatenhandel BV Spaarnwouderstraat 41/A 2011AB Haarlem |

Very nice build Peter. I found the Picasa link did not work, but found this worked ok. |

It seems this could make a good tent stove. Presumably if you placed a metal plate over the hole rather than a pot, it could also function as a heating stove as the outside body would heat up.

Post deleted. I should have looked at the Picasaweb photos first.

I cannot find one as big as the one you used. The largest pail is 25 litres with a top dia of 12". Was your supplier difficult to find, and do the do the manufacturing? I cannot find a website for them. I can find a 60L drum, but that is much more costly for packaging as they cannot be stacked inside each other It appears you used another one or two sizes of pail to make the internal parts of the heater. PICTURE. Can you recall the sizes? It looks such a nice stove, and it would be ideal for the catering at a RMH workshop. I wish I had had one when we used to run charcoal making courses. |

woodburner, I am also looking for a similar pail in the UK, can you tell me where you found the 25 litre one? Am gathering materials to build a sturdy but lightweight rocket for a travelling bike trailer field kitchen. Will probably stick with the more tradional winiarski style stove rather than the institutional with chimney, although the possibility of using inside a canvas tent as a heating stove in the future makes this design interesting to me.

The supplier of the drum don't make it themselves, it's a trading company. Very small, in an obscure corner near the town center of Haarlem. I've found them via a Dutch equivalent of Ebay. It's not necessary to use a pail for the drum, it have been just a coincidence in my case.
The smallest pail, which do contain the combustion chamber is a 10 liter item 230 x 280 mm, acquired from the local chinese restaurant around the corner, containing peanut butter. The slightly larger pail is a a 20 liter item, 290 x 310 mm, new and the same size as another one containing cold tar for driveways. The new one I've found as an orphan beside a garbage bin.
It won't be easy to find a source of these parts. Maybe a refurbishing company?

For those in the UK who want to build this stove, [this was] a bin of the right size for the outer. Only problem is the lid as I see it.
The link no longer works, see later posts
