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.

Abstract: This invention relates to a gas burner which employs a two stage flame stabilizer. At low input rates, a fully aerated flame is stabilized at the surface of a porous material. At higher input rates, the flame blows off and is held by flame stabilization tabs. Such structures of this type, generally, operate over a very wide range of input rates and employ a highly aerated flame which reduces the flame temperature, slows NOx production, and increases the overall reaction rate by shortening the flame while reducing carbon monoxide (CO) caused by flame impingement.
