Description

 

IMAGE. A typical laboratory gas burner.

A gas burner is used to heat non-flammable objects or solutions. It can be used to heat objects to very high temperatures. Temperatures in the hottest region of the burner exceed 1000°C.

A gas burner can be used to:

  • heat aqueous non-flammable solutions

  • fire-polish broken glass

  • dry hydrated salts

  • melt samples

  • heat salts to observe emission spectra

Methane (CH4) gas is fed into the burner through the gas inlet. The gas control needle valve controls the rate at which methane enters the burner. The rate at which air enters the burner is adjusted with the air control vent. Methane and oxygen mix in the burner tube and, when ignited, produce a flame.
