    Abstract: Horizontally arranged burners for boiler furnaces are provided where each burner includes a fuel nozzle surrounded by a secondary air outlet. The fuel nozzle and secondary air outlets may tilt in tandem with respect to an air plenum supplying inner secondary air and a fuel carrier providing fuel. Also provided are outer secondary air buckets that may independently tilt with respect to a frame connected to the air plenum. This arrangement can be installed as a retrofit in a conventional horizontal furnace system or in a newly built system. The fuel nozzle and secondary air outlet, and secondary air buckets may all tilt in unison or may all tilt independently. The tilting assists with optimizing a flame temperature profile within the furnace.

    Abstract: A flame retaining nozzle tip for a burner for a pulverized fuel fired furnace receiving a primary stream of pulverized fuel and primary transport and combustion air for discharge into the combustion zone of the furnace comprises a hollow, open-ended, choke or body having an inlet end of generally polygonal flow cross-section for receiving the stream and an outlet end of generally rounded cross-section for accelerating and discharging the stream into the furnace. The outlet end of the choke has a flow cross-sectional area that is less than that of the inlet end to provide choking action. An elongated center element is mounted in coaxial alignment with a central axis of the choke body extending between the inlet and outlet ends. A plurality of swirl vanes are mounted around the central axis and are angularly disposed relative to the general flow direction with inner edges of the vanes spaced equilaterally around and connected to the central element and outer edges connected to the inside surfaces of the choke body. The vanes cause the stream of primary air and pulverized fuel to rotate rapidly around the central axis as the stream passes through the outlet end.

    Abstract: A low-nox burner for use in industrial furnaces and/or boilers which burn pulverized coal. The burner includes a burner tip which divides an annular pulverized coal stream into alternating fuel-rich and fuel-lean streams. The tip includes a plurality of alternating main and secondary blade members which are skewed to produce rotational movement in the streams. The main blade has a leading edge that is aligned with a radial vector extending through a center axis of the burner and a trailing edge that is tilted with respect to the radial vector in order to define a substantially planar surface between the leading and trailing edges. The secondary blade includes leading and trailing edges that are both aligned with radial vectors and defines a twisted surfaces between the edges. The secondary blade is skewed with respect to the longitudinal direction by an angle that is substantially greater than the angle at which the main blade is skewed. As a result, channels having converging cross sections are defined between the main blade and one adjacent secondary blade, and diverging channels are defined by the main blade and another adjacent secondary blade. During operation, the tip creates a fuel-rich zone surrounded by a fuel-lean zone in the combustion region.
