We only use gas for our cooker, which will work with Butane or Propane. Which type should we use?
However, here's the maths comparing 7kg butane cylinders with 6kg propane:Butane burns hotter than propane by approx 16 degrees academic nonsense really when you consider the overall temperature of a flame.
As mentioned at low temperatures around 5 degrees butane has difficulty gassing so propane is the better choice.late autumn to early spring
Temperature can only affect the reaction rate (below gassing point, that rate will be zero and the rate will increase with increasing temperature until the point at which the gas explodes). However, the total amount of energy remains unchanged. A 7kg cylinder of butane can provide 343.7 MJ of heat energy; a 6kg cylinder of propane can provide 302.4 MJ. The amount of energy per unit mass is the definition of "calorific value" and is completely independent of temperature (or pressure).Of course temperature matters getting back on topic we both agree butane has difficulty gassing at low temps so temperature does have an affect.
Butane is summer gas propane is winter.as a general rule
Do people still use those piddly little bottles? Far better value to use the ones that are about twice the size for very little more money.However, here's the maths comparing 7kg butane cylinders with 6kg propane:
Makes perfect sense for those who can fit bigger bottles into their gas locker... many of us don't have the luxury of that choice.Do people still use those piddly little bottles? Far better value to use the ones that are about twice the size for very little more money.
