How hot is the safety flame?

3,100 °F
In a laboratory under normal gravity conditions and with a closed air inlet, a Bunsen burner burns with yellow flame (also called a safety flame) with a peak temperature of about 2,000 K (3,100 °F). The yellow arises from incandescence of very fine soot particles that are produced in the flame.

Which is the hottest zone of Bunsen burner?

The hottest region of Bunsen flame shown in the figure region 2. It is just above the tip of the primary flame. It reaches about 1,500 °C (2,700 °F).

Why is a Bunsen burner flame hotter?

Increasing the air flow to the burner produces more complete combustion and a hotter flame. The air is increased by opening up the air vent (turning the metal collar). The air is drawn into the barrel of the burner by the gas coming out of the gas jet. The gas-air mixture is then ignited above the barrel.

How hot is blue fire?

When natural gas is ignited in a stove burner, the gases quickly burn at a very high temperature, yielding mainly blue flames.
