A Bunsen burner, named after Robert Bunsen, is a kind of ambient air gas burner used as laboratory equipment; it produces a single open gas flame, and is used for heating, sterilization, and combustion.
The gas can be natural gas (which is mainly methane) or a liquefied petroleum gas, such as propane, butane, a mixture or, as Bunsen himself used, coal gas. Combustion temperature achieved depends in part on the adiabatic flame temperature of the chosen fuel mixture.
