ABSTRACT:
An inshot gas burner nozzle having a flame retention insert that enhances flame stability and reduces noise, the insert comprising a central opening, secondary openings of smaller diameter arranged circularly around the central insert, and a plurality of restricted peripheral openings in the form of stepped notches. The nozzle further comprises plenum chambers which have restricted outlets thereby creating back pressure within the plenums to improve cross-ignition of adjacent nozzles.
