Gasoline can be ignited by even a tiny spark at temperatures as low as fifty below zero, but it merely evaporates at temperatures up to about four hundred seventy five to five hundred F. At that temperature, it ignites spontaneously.
With enough oxygen, you get complete combustion and an LPG (Propane) flame burns at a temperature of around 1,980Â°C. For Natural Gas (Methane), the temperature is about 1,960Â°C. A yellow gas flame is indicative of incomplete combustion and carbon monoxide emissions. Yellow gas flames only burn at around 1,000 Â°C.
