Burning temperature


At http://en.wikipedia.org/wiki/Gas_burner it writes that pure propane burns at 1,980 °C and pure butane at 1,970 °C but propane/butane burns at 1,225 °C. Why does the mixture burn at a much lower temperature?

Because the writers of Wikipedia articles can make up and use any numbers they want to?

There are a number of different ways to measure flame temperature, as well as different conditions. If you try to compare numbers from measurements done in different ways, you'll find that there is not much meaningful in the comparison.


This is what you wamt to look in

This shows fairly close values for several gaseous fuels

Perhaps it has something to do with oxygen affinity. I really don't know though.
