BURNER FOR NON-SYMMETRICAL COMBUSTION AND METHOD

摘要

A burner (10) and method for non-symmetrical combustion generally includes a burner housing (11) enclosing a burner plenum (14). A fuel conduit (30) extends longitudinally within the housing and is positioned coaxial with a line spaced from a central axis of the burner. The fuel conduit defines a fuel exit opening (31). An air conduit (36) extends into the housing and defines an air opening (37) on an opposite side of the burner central axis from the fuel exit opening. The air opening is positioned a greater distance away from the burner central axis than the fuel exit opening. The air conduit has a cross-sectional shape in the form of a segment of a circle (figure 2). A baffle (28) is positioned at least partially around the fuel conduit and defines the air conduit. A burner port block (24) is connected to the baffle downstream of the fuel exit opening. The burner port block has a sidewall (26) diverging from the burner central axis (1), with the sidewall diverging at a flare angle of between approximately 2 degrees and approximately 30 degrees.
