bbq: i got a new bbq but i cant get a propane cylinder. can i use butane on it instead? whats the difference in the the two gases anyway?|||Butane and Propane are both LPG, liquid petroleum gas and the basic difference is that propane will vaporize at a lower temperature, so is used in northern, colder climates. You cannot even buy pure butane that isn't a blend of propane and other hydrocarbons. The regulators and orifices are usually the same. The confusion comes from when switching from LPG to natural gas the orifices have to be switched to larger ones because natural gas doesn't have enough btu's to do the job of one fifth as much LPG. Not because of an explosion hazard. If you can find a butane cylinder that will fit your BBQ, use it, although I am surprised to hear you can't get a propane cyl. Edit: If the existing regulator fits the butane tank that should tell you something.|||If it is , as I understand, one of these gas bottle jobs, it is NOT a barbeque. It is a gas cooker. Get one that uses charcoal / wood. Otherwise, for flavour you might as well use the kitchen cooker and serve it outdoors.|||Of course you can get propane! Every tool hire shop stocks it. Also look up 'bottled gas' in yellow pages. They will usually deliver for free. Butane will not work in a propane burner. Different jets and pressure.|||im not sure what the exact difference is but i do know they use different regulators and you gas grill is designed for propane. just like antural gas an propane use different regulators.|||Only if you want it to go .... BOOM!! The orifice is different for each gas type. The orifice for butane may be to large and allow to much gas to escape at one time. Butane will also leave a very nasty taste.|||No, both burner jets and pressure will be different and propane will burn hotter and may melt the stove. Strictly speaking these devices are not barbecues, they are gas cookers.|||i dont think you can still buy butane, butane freezes in cold weather, they quite making it, but yes its basically the same
