摘要： A powdery fuel combustion apparatus disposed on furnace side plane (7) of vertical square body type furnace in which a vertical plane passing through a fuel jetting directional axis (8) does not cross the furnace side plane orthogonally, and thus the workability of furnace wall tubes and burner panel, and the maintainability of burner nozzle are improved. The apparatus includes a burner nozzle (1) that is formed such that the nozzle has right and left non-symmetrical shapes, with respect to a vertical plane passing through axis (8). Also, the nozzle has a tip portion opening lying in an opening plane (2) which coincides or is parallel to the furnace side plane (7).

摘要： A burner for combustion of a pulverized coal mixture having two kinds of rich and lean concentration has a height of a burner panel reduced and the overall burner simplified. A rich/lean separator (10, 20, 30) is provided within a pulverized coal conduit (2) so that a high concentration mixture is formed in an outer peripheral portion and a low concentration mixture is formed in a central portion within a single pulverized coal conduit. Thus, a rich mixture burner and a lean mixture burner, which have been conventionally provided separately, may be formed into a single burner. Recirculation of air is accelerated by a cutaway slit (20d, 30d) provided in a central portion of the rich/lean separator to make the air flow rate distribution uniform in a pulverized coal nozzle. Also, a duct and an air blow box for the combustion air to be supplied to the pulverized coal flame are not integrally formed continuous in the height direction, but are divided into a plurality of discontinuous units.

摘要： A pulverized fuel combustion burner includes a pulverized fuel and air mixture conduit. A pulverized fuel rich/lean separator is disposed at the axial center of the conduit so that a high concentration mixture is formed at an outer peripheral portion of the conduit and a low concentration mixture is formed at a central portion of the conduit. The pulverized fuel rich/lean separator has a cross-sectional shape which gradually enlarges in the flow direction at an angle to the flow direction. It becomes parallel to the flow direction downstream of the enlarging portion, and terminates in a flat surface that is perpendicular to the axis of the separator. A passage extends through the pulverized fuel rich/lean separator along the axis.

摘要： To provide a low combustibility fuel firing burner that can ensure high ignition performance and combustion stability even if a gas flow rate is changed along with changes in boiler load or the like. A low combustibility fuel firing burner separates a pulverized low combustibility fuel supplied together with an air with a separator, distributing the separated fuel to a rich portion nozzle and a lean portion nozzle provided in a furnace, and burning the fuel, in which a variable control part such as a core or a flow adjusting/blocking valve is provided in at least one of a high-particle-concentration gas pipe extending from a downstream side of the separator and communicating with the rich portion nozzle and a low-particle-concentration gas pipe extending from the downstream side of the separator and communicating with the lean portion nozzle.
