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.
