Abstract
A combined fuel distribution and flameholding system (14) includes an improved spraybar (16) having a tapered portion (28) and a radially inwardly disposed tip portion (30). The tapered portion (28) is configured to provide a flow profile (26) diminishing with respect to inward radial displacement from the burner wall (32) for achieving a uniform blockage to free flow area ratio within the burner. The tip portion (30) creates a turbulent or pilot region (32) in the center of the burner, providing a local environment well suited for ignition and low load burner operation. The individual bars (16) are releasable (46) from the exterior of the burner for allowing longitudinal withdrawal of the entire spraybar (16) through a corresponding opening (48) in the burner wall (22).
