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.
