Bunsen burner, gas burner, commonly used in scientific laboratories, consisting essentially of a hollow tube which is fitted vertically around the flame and which has an opening at the base to admit air. A smokeless, nonluminous flame of high temperature is produced. The underlying principle of the Bunsen burner is basic to common gas stoves and lamps.
