Haha Kev beat me by 30 secs!

[Kevco5]

41 secs actually don't you know!

I use propane with my own, I think it's an issue with the freezing point of butane so prolonged use outdoors on a cold day can cause the pressure to drop.

[Ciderhead]

It has a lower freezing point and is more effective in low temps.
Still don't understand why everyone isn't using elecky

[Ciderhead]

Butane at 10+ degrees ambient is 12% hotter than propane.

[Will_D]

Butane freezes in prolonged hard frosts but otherwise has a slight edge. Burns hotter and lasts a bit longer. Also a bit easier to get.

Jaysus it must get could beyounf the pale!
Butane freezes at about -135C. It boils at about -1C

[LordEoin]

Aye, it doesn't freeze it just stops 'gassing off'.
When you hit the butane's boiling point at -1C it's more like a simmer with very little gas steam. over about 4-5C it'll be give off much more gas 'steam', like water at full boil. but you need ambient temps a few degrees higher.

Propane will 'boil' at about -45C, so there's never any danger of it not gassing off.

And on the original question, you can often find good strong gas rings in hardware stores or co-ops too. I think they're used for melting tar or something similar.

thanks for the replies, is the reg just to control the flame height?
In one pic from hamiltons it had a turn screw type thing to control flow. same thing?

For these burners running on a standard yellow butane bottle you need the adjustable reg that they sell (for a few quid more) as the fixed 37 mbar reg will generate a whole lot of soot!

It allows you to compensate for outside air temperature and get the flames you want
