(57) Abstract:
A low NOx burner nozzle assembly for a radiant wall
burner includes an elongated hollow burner tube and
a discharge nozzle. The burner tube defines a conduit
for supplying a mixture of fuel and air to a radiant
combustion area. The discharge nozzle is mounted on
the tube at the downstream end of the conduit and
adapted for directing the mixture of fuel and air in an
essentially radial direction. The discharge nozzle
includes a plurality of flow directing members
arranged in an array to define there between a
plurality of passageways which extend in a generally
radial direction and having different respective flow
areas. The discharge nozzle also has an end cap to
prevent axial flow of the primary air/fuel mixture.
The end cap has an axially extending hole therein,
and the nozzle assembly includes a staged fuel burner
nozzle arranged so as to protrude axially through
such hole.
