Elecopto Bunsen burner sheet base with stop cock Laboratory Bunsen Burner

The designers of the building intended to use the gas not just for illumination, but also in burners for laboratory operations. For any burner lamp, it was desirable to maximize the temperature and minimize luminosity. However, existing laboratory burner lamps left much to be desired not just in terms of the heat of the flame, but also regarding economy and simplicity.Bunsen burner flames depend on air flow in the throat holes (on the burner side, not the needle valve for gas flow)1. air hole closed (safety flame used for lighting or default), 2. air hole slightly open, 3. air hole half-open, 4. air hole fully open (roaring blue flame).
