REGENERATIVE BURNER FOR NON-SYMMETRICAL COMBUSTION

摘要

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.

1. A burner for non-symmetrical combustion, comprising:
a burner housing enclosing a burner plenum; a fuel conduit extending longitudinally within the housing and positioned coaxial with an axis spaced from a central axis of the burner, with the fuel conduit defining a fuel exit opening; an air conduit extending into the housing, with the air conduit defining an air opening on an opposite side of the burner central axis from the fuel exit opening; and a baffle positioned at least partially around the fuel conduit and defining the air conduit, wherein the baffle further defines a cavity immediately adjacent the fuel exit opening and in fluid communication with the fuel conduit through the fuel exit opening, and wherein a sidewall of the baffle defining the cavity converges from the axis of the fuel conduit.
