Abstract: Regenerative burner for non-symmetrical combustion and a method of firing the burner. The burner includes a burner housing enclosing a burner plenum; a fuel conduit extending longitudinally within the housing and positioned coaxial with a line spaced from a central axis of the burner, with the fuel conduit defining a fuel exit opening; and a baffle positioned at least partially around the fuel conduit and defining an air conduit extending into the housing and defining an air opening on an opposite side of the burner central axis from the fuel exit opening. The baffle also defines a cavity adjacent the fuel exit opening and in communication with the fuel conduit through the fuel exit opening. The sidewall of the cavity converges from a central axis of the fuel conduit to provide further jet penetration into the furnace and achieve greater levels of products of combustion entrainment prior to combustion.

Abstract: A burner for non-symmetrical combustion generally includes a burner housing enclosing a burner plenum. A fuel conduit extends 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. A baffle defining an air conduit extends longitudinally within the housing. The air conduit has an air opening on an opposite side of the burner central axis from the fuel exit opening. At least one oxygen injection lance extends longitudinally within the housing and partially through the air conduit. A burner port block is located adjacent to the baffle and downstream of the air opening, and is in fluid communication with the fuel conduit and the air conduit.

Abstract: A burner (10) for reducing NOx emissions where supply fuel (16) and supply air (20) are supplied to a combustion tunnel (52) at high and low velocities and secondary air (26) is supplied to a secondary combustion zone (60), wherein products of combustion (59) exiting into the secondary combustion zone (60) from the combustion tunnel (52) are drawn back into the combustion tunnel (52) and back into the secondary air conduit (54).

Abstract: A burner for non-symmetrical combustion includes a burner housing enclosing a burner plenum. A fuel conduit 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. An air conduit extends into the housing and defines an air opening 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. A baffle is positioned at least partially around the fuel conduit and defines the air conduit. A burner port block is connected to the baffle downstream of the fuel exit opening. The burner port block has a sidewall diverging from the burner central axis.
