Has anyone on here tried making a stove out of spent gas cylinders, ie propane etc. There are a few bits I have found on the web, but can anyone reccommend a particular website?

If you survive the initial cutting of the cylinder why not try making it into a gasifier? Chimney at the bottom, a mid shelf with small vents and a lever to open a bypass for lighting.

im rather pensive at the moment, h,,mmmmmm..there have been reports as of late,of night time explosions and things hurling spacewards, i wonder if there is a connection to the fact that some irish bodgers have gone missing.some have left to go for a gas refill and not returned,the wives thinking they had absconded leaving them with no gas for cooking the dinner.  it might set their minds at rest to realise that patrick in his loving ways decided to take the cylinder and return home with a new stove,sitting on it to hold it while he cut into it with the grinder.concentrating hard on heating the house and keeping his loved ones warm,he would have been smiling to himself,thinking ,how surprised his wife would be at his brilliant bodging.instead he took off with a whoooosh and a bang  .meanwhile we have been asked by the met office to look out for space droppings.  . could there be a link,?? |

Whats a gasifier? I would be interested in your forge/foundry thing. I'll keep you posted on how we get on.
Nice one Biff! I think we will be filling the uncorked bottles with water to make sure all the gas is out.

Whats a gasifier? http://en.wikipedia.org/wiki/Wood_gas_generatorEssentially, you burn wood in the presence of a very limited air supply. The oxygen is completely used, and due to the very incomplete combustion, a lot of CO (Carbon Monoxide) is produced. I believe if you get the temperature right, then you also get some hydrocarbons from decomposing the long chains in the wood. Bulky, dangerous (CO is very toxic), dangerous (get it wrong and you have a container of combustible fuel/air mix), and of course absolutely not a "turn the key and drive off" system ! On the other hand, given how the price of petrol is going ... |

Aha! I have come across that used during WW1 to power vehicles - Woodgas.

I was thinking of something slightly different, a gasifier stove that burns the gas underneath which in turn dries the fuel and drives out more gas. There are only a few commercial gasifier stoves available and they are very expensive. If making a homemade stove it would be nice to experiment with this kind of system. www.fireplaces.co.uk/product-xeoos-x5-natur.php |

Another thing worth considering is making a sawdust stove. These are very interesting, and I planned to make one last winter, but never got round to it - very cheap fuel, as most people don't want sawdust, and you don't have all the woodstove owners queuing up to buy it - and one fill will last 12-18hours burning.

What special needs does a sawdust stove have above a normal one? It would certainly solve the problem of all that sawdust either going to waste or trying to compress it.

The two special needs are:
1)The flue gases go up the centre,insulated from the stove body by all the sawdust. So you need to do another pass of the flue gases down the OUTSIDE of the burning chamber. This means a double-bodied stove.
2)You need to be able to remove the top of the stove in order to reload the fuel. The fact that the exhaust exits at the base of the stove means that this isn't such a problem as you think it might be, but it needs to be airtight, and thick metal to withstand the high temperature gas that's constantly hitting it
A exhaust suction fan might be worth considering to reduce the chances of backdraught etc.
