ABSTRACT:
An industrial process burner which operates with optimal control of fuel/air mixing and reduced NO.sub.x emissions. The burner has a body formed with a primary fuel jet which is surrounded by inner and outer sets of air jets. The inner set of air jets directs air for mixing with the primary fuel jet. The outer set of air jets directs air which entrains a portion of combustion products for diluting the pre-combustion air/fuel mixture to lower the flame temperature and reduce NO.sub.x emissions. A secondary set of fuel jets directs fuel along a path apart from the primary fuel jet, and a set of additional air jets merges into and deflects air flow from the secondary jets inwardly to the base of the primary fuel jet for establishing a local combustion zone to promote ignition of the flame.
