ABSTRACT:
A burner construction for low emission burners in which the primary fuel is injected with air in an annulus into the upstream end of the burners so as to cause a significant recirculation of the fuel and air mixture adjacent to the end cap, the secondary fuel is injected into the burner in a small angle spray at a point substantially spaced from the end cap and large combustion and/or dilution holes in the burner wall a small distance upstream of the secondary nozzle are sized to produce an additional recirculation in the primary fuel and air around the secondary nozzle with this additional recirculation in the direction opposite to the first recirculation.
