A gas burner of the type a premixed and a control of the flame and use of this burner in particular for installation a tube immersed

摘要

A gas burner of the air and combustible gas mixture type includes a flame control cell mounted away from the actual flame. The control cell, by being located away from the actual flame, can monitor the operating conditions of the flame and, in response thereto, controls the flow of air and gas, the firing of the lighting electrode and the regulating of the gas intake valve. The control cell is further protected from the flame and any possible backfires by a pressure differential existing between the injected air and combustible gas mixture.
