Abstract
A burner includes separate fuel and oxidant conduits. The fuel conduit has inlet, transitional, and outlet sections, and the oxidant conduit has inlet and outlet sections. The burner has a longitudinal axis and including a burner tip having a first elongated edge adjacent a flow of the fuel, and a second elongated edge adjacent a flow of an oxidant and forming a primary tip angle (α) of less than about 15° from a line parallel to the longitudinal axis and intersecting an upstream surface parallel to the longitudinal axis. The first elongated edge and the second elongated edge form a secondary tip angle (β) greater than the primary tip angle (α) and less than about 90° from a line tangent to and extending from the first elongated edge in the direction of the flow of the fuel.
