摘要： PROBLEM TO BE SOLVED: To provide a pulverized coal burner which keeps the rich/lean balance firm in the pulverized coal formed within a pulverized coal tube against changes in the angle of a pulverized coal nozzle in a pulverized coal burner which has the pulverized coal tube to convey a mixed gas of the pulverized coal and air and the pulverized coal nozzle arranged free to rotate at the tip part thereof.
SOLUTION: A pulverized coal nozzle 04 is arranged free to rotate centered on a pin 08 at the tip part of a pulverized coal tube 01 for conveying a pulverized coal mixed gas 02. A rich/lean separator 03 is disposed in the pulverized coal tube 01 to separate the pulverized coal mixed gas between rich and lean levels. On the downstream side thereof, is arranged a flow straightener 10 which lets a lean mixer pass through an internal path while a rich mixed gas passes through the outer circumference part thereof and a partition plate 09 is arranged on the downstream side thereof to guide the lean mixed gas passing through the internal path of the flow straightener 10 into the pulverized coal nozzle 04. This keeps the rich/lean balance of the pulverized coal mixed gas against angular changes in the pulverized coal nozzle 04.

摘要： PROBLEM TO BE SOLVED: To provide a fine powder-like fuel combustion device capable of providing excellent ignition and combustion performances by sufficiently developing the function of a concentrated/lean fuel separator to eliminate the unbalance of the concentration of fine powder-like fuel (fine powder coal) in the fine powder-like fuel combustion device such as a fine powder coal firing burner having an asymmetrical burner nozzle.
SOLUTION: This fine powder-like fuel combustion device comprises the burner nozzle 1, a fine powder coal supply tube 3, and a wind box 5 forming a combustion supporting air supply passage 4 around the fine powder-like fuel supply tube. A vertical plane passing the axis 8 of the jetting direction of the mixed flow A of fine powder coal and carrying air is tilted without crossing the side face of a furnace at a right angle. The shape of the burner nozzle is laterally asymmetrical with respect to the vertical plane, and a burner nozzle opening face 2 is positioned in the same plane as the side face of the furnace. The concentrated/lean fuel separator 31 is horizontally installed in the burner nozzle or the fine powder coal supply tube. The concentrated/lean fuel separator 31 is installed to be parallel with the side face of the furnace and laterally asymmetric with respect to the vertical plane.
