ABSTRACT:
An atmospheric gas burner produces improved flame stability by establishing a higher pressure drop pilot flame at at least one burner port. The burner has a preferably recessed pilot port which is isolated from the primary burner ports. A small portion of the total fuel introduced to the burner is directly fed to the pilot port without entrained air. Consequently, the pilot port supports a high pressure drop diffusion pilot flame which is better able to withstand ambient disturbances. Then in the event that a momentary disturbance extinguishes the primary flames, the pilot flame will serve as a reignition source.
