Gas bottle stove with character!

Steg · Apr 21, 2009

Thought I would post some pic's of my prototype woodburning piggy!

The stove has been made from a 15kg gas bottle. The flue is a 4" exhaust pipe, legs are 40mm x 5mm steel tube and the hinges are some 25mm x 5mm flat bar.

I have reworked the stove by installing a flame baffle (pic 2) inside to prevent the flames going straight up the flue and wasting heat. The second reworking was cutting a 150mm square out of the top and welding in a flat plate section to for a hot plate for a small pan or kettle.

Piggy breathes through his legs (pic 3 & 4) and further flame controls are a flue damper (pic 5) and two position door latch (closed or 10mm open).

He has a serious appetite for wood, but in return rewards you with load's of heat and glowing a faint cherry red in the evenings!

I have no objection to you copying the pig. I used a 115mm grinder with 1mm thick cutting disc and jigsaw with a good quality (Bosch) metal cutting blade.

what diameter pipe did you use for legs and what size holes? :welder:

Arsonista · Apr 21, 2009

There are so many stoves that all look the same. Yours really stands out from the crowd. Really like the vents in the legs. :clapping:

Never thought I'd see a gas bottle look cute.

The pipe is 40mm diameter with 5mm wall (just some i had kicking about).

The holes in the underside of the legs are 12mm diameter and there are 3 in each leg and the holes in the gas bottle at the top of the legs are 30mm.

There is only one problem with the holes in the legs - you can knock hot embers down the legs when stoking the fire, I managed to char a nice circle about 15mm deep on my wooden decking :ashamed:

if its needed on the decking it now sits on old ceramic tiles.

On the next version I will make the legs longer and possibly weld them on the gas bottle a little higher up the sides or i would maybe install mesh over the leg holes.

The leg air intakes or not really nessesary but they do help with a secondary burn (burning smoke to give a cleaner flue output) in the top of the burner as would leaving about 40mm of flue sticking down into the top of the burner.

Any questions, just ask, and post a pic when your done.

The way i degas the bottles is to make sure there is no pressure left in the bottle, remove the valve, fill the bottle with water to the brim and then leave for a day. Turn the bottle over and let it drain and then leave it upside down for a further day.

P.S. be careful where you drain the water, it really smells horrible and will smell for days.

Hi,

could you have inserted the legs inside the bottle by, say, three inches, so the open top is above the embers? That way it's less likely that something will fall down a leg and it'd be easier then getting mesh over each hole.

As I recall from an earlier discussion on stoves, wood burns better if the air holes are above the fire, or have I mis-remembered that?

Regards
Peter

Wood does burn better with air from above, and this burner is no exception, when fueled on dry seasoned wood it will reduce virtually all wood to fine ash with very few charcoal lumps left over.

As for inserting the tubes into the bottle - what a good idea, thanks for the suggestion, I will use that on piggy MK2. It would probably only need about 1" - 1.5" inside the bottle, after all, if I had been a little less hamfisted I wouldn't have knocked the embers down the leg anyway :ashamed:
