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.

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： An object of the present invention is to provide a combustion apparatus in which a space which does not contribute effectively to the combustion of fuel is less prone to be produced in a furnace because burners are not disposed at the corners of the furnace.The furnace having a square horizontal cross section is provided with the burners so that an in-furnace injection direction axis line of the burner is tangent to an imaginary circle. The burner is disposed at one place on a front wall, rear wall, right side wall, and left side wall of the furnace each, at a total of four places. The burner on each wall is installed so that the intersection of the in-furnace injection direction axis line of the burner and the furnace wall surface is apart from a furnace corner (corner point) by a length L1. The value of the length L1 is 15% of a length L of one side of width of the inside wall of the furnace when the furnace is viewed from the top.

摘要： A pulverized fuel combustion burner and furnace arrangement has a plurality of air nozzles arranged on a side wall of the furnace for injecting a mixed flow of pulverized fuel and carrier air to establish a flame into the furnace. The plurality of nozzles includes a primary nozzle for injecting the mixed flow into the furnace and a secondary nozzle positioned around the primary nozzle for feeding combustion auxiliary air around the primary nozzle. A pulverized fuel supply pipe feeds the mixed flow to the primary nozzle. The primary nozzle and the pulverized fuel supply pipe are joined at a jointed portion at which the primary nozzle can be pivoted to change a direction for injecting the mixed flow into the furnace. The pulverized fuel supply pipe extends through a windbox, the windbox forming a combustion auxiliary air supply passage around the pulverized fuel supply pipe. A rich/lean flow separator is disposed in a middle portion of the pulverized fuel supply pipe spaced from opposite inner walls of the pulverized fuel supply pipe such that when the mixed flow flows around the rich/lean flow separator, a rich/lean flow concentration distribution is established in which a fuel-rich flow is created at an outer part inside of the pulverized fuel supply pipe and adjacent to the opposite inner walls and a fuel-lean flow is created at an inner part inside of the rich flow and along a center line of the pulverized fuel supply pipe. Flow straightening plates are disposed and positioned in the primary nozzle and the pulverized fuel supply pipe downstream of the rich/lean flow separator so as to maintain the rich/lean flow concentration distribution established by the rich/lean flow separator to the exit of the primary nozzle.
