The maximum temperature of a Bunsen burner flame is 1500 degrees Celsius, or 2700 degrees Fahrenheit, according to Encyclopaedia Britannica. The warmest part of the Bunsen burner flame is located above the tip of the primary flame.
The Bunsen burner combines flammable gas with controlled bursts of air to produce a warmer flame than room air and gas alone. The mixture of air and gas in the burner is approximately one part gas to three parts air. This mixture is forced to the top of the burner's tube through gas pressure and is lit with a match. The flame of a Bunsen burner is blue, and its outer ring can become colorless due to oxidation.
