Abstract
A burner nozzle having a hot face, side surfaces, and a plurality of internal gas flow passages and comprising a plurality of slits oriented in at least two different directions, wherein a selected number of the slits are formed in the hot face and/or side surfaces. The optimized location and depth of the slits relieve stresses that arise from temperature differences within the burner nozzle, caused by operation in high temperature furnaces, thereby extending the life (time to failure by fracture) of the burner nozzle.
Claims21
A burner nozzle having a hot face, side surfaces, and a plurality of internal flow passages, the burner nozzle comprising a plurality of slits oriented in at least two different directions, and a selected number of slits, having a depth and location, formed in the hot face.
A burner nozzle having a hot face, first and second side surfaces, and plurality of internal flow passages that terminate in the hot face, comprising:
- at least one front stress slit formed in the hot face, positioned between adjacent internal flow passages, and at least one stress slit formed in each side surface.
