What is the coldest temperature a flame can be?
I know some gasses burn hotter than others but there must be a lowest temperature burning gas?

clever Q. never though of that
but rusting is burning iron in Oxygen
it gives off delectable infra red radiation
any reaction that gives off energy gives off heat and has a temperature depending on how well the heat is insulated before energy generation = output balance is achievedSource(s): got me thinking

As far as I know paper has a natural ignition point at 451degrees F. This is the coldest I know of...However wood may be colder ?
Here is a table from one of the Google sites....
Fuel Gas Combustion with Oxygen
(oC) Combustion with Oxygen and with Air
Acetylene 3,100... 2,400
Carbon Monoxide ...2,121
Hydrogen 2,660 ... 2,045
Methane 2,810 ... 1,957
Natural Gas ... 2,770
Propane 2,820 .... 1,980
Propane Butane Mix .... 1,970
Propylene .... 2,870
