ABSTRACT:
A flashback resistant burner for lean fuel/air mixtures includes apparatus for mixing a primary fuel and combustion air to form a noncombustible fuel/air mixture. Means are provided for accelerating the noncombustible fuel/air mixture to a velocity higher than the flame speed of a combustible mixture of the primary fuel and air. Means are further provided for mixing a secondary fuel with the accelerated noncombustible fuel/air mixture to form a combustible fuel/air mixture that has an equivalence ratio less than 1. Means are then provided for burning the combustible fuel/air mixture.
