    Abstract: This invention provides a solid fuel burner, which, while rendering the c apacity larger than that in the prior art, can suppress an increase in an un ignited region and thus can realize the prevention of an increase in NOx den sity in a combustion gas and the prevention of a lowering in combustion effi ciency, and a combustion equipment and boiler comprising the burner. The bur ner comprises a fuel-containing fluid supply nozzle (12) which supplies a fu el-containing fluid, from a connection part in a fluid transfer flow passage (10) for transferring a fuel-containing fluid comprising a fuel and a mediu m for the transfer of the fuel, toward an outlet part provided on the wall o f a furnace (4). The fuel-containing fluid supply nozzle (12) in its cross s ection perpendicular to the direction of flow of the fluid is in a rectangul ar, elliptical, or approximately elliptical form having major and minor axis parts from a connecting part (10a) in the fluid transfer flow passage (10) toward the outlet part provided on the wall surface of the furnace (4). Furt her, the area of a cross section perpendicular to the direction of flow of t he fluid is gradually increased from the connecting part in the fluid transf er flow passage (10) toward the outlet part. One or more air supply nozzles (15) for supplying combustion air are providedon the peripheral part of the nozzle (12).

    Abstract: An apparatus which comprises a burner (1), through which pulverized coal and carrier air are passed to be burnt in a combustion chamber (2), and a flame retainer (18) disposed at an end of the burner. The flame retainer includes a flared tube (17) and an annular plate (16), which plate has a plurality of parts projecting radially inwards and being equiangularly spaced from each other. The annular plate comprises a plurality of ceramic pieces (23) and a plurality of fastener elements (25), both of which are arranged and assembled alternately to form the annular plate. The ceramic piece is shaped such that it projects radially inwards to serve as the projecting part when assembled. The ceramic piece has at opposite sides thereof smoothly curved edge surfaces (24a, 24b), and the fastener element has at opposite sides thereof smoothly curved edge surfaces (26a, 26b) which are engaged with the curved edge surfaces of the two neighbouring two ceramic pieces.

    Abstract: The present invention provides a solid fuel burner, which, while rendering the capacity larger than that in the conventional art, can suppress an increase in an unignited region and thus can realize the prevention of an increase in NOx concentration in a combustion gas and the prevention of a lowering in combustion efficiency, and a combustion equipment and boiler including the burner. The burner includes a fuel-containing fluid supply nozzle (12) which supplies a fuel-containing fluid, from a connecting part in a fluid transfer flow passage (10) for transferring a fuel-containing fluid including a fuel and a medium for transfer of the fuel, toward an outlet part provided on the wall of a furnace (4) . The fuel-containing fluid supply nozzle (12) in its cross section perpendicular to the direction of flow of the fluid is in a rectangular, elliptical, or substantially elliptical form having major and minor axis parts from a connecting part (10a) in the fluid transfer flow passage (10) toward the outlet part provided on the wall surface of the furnace (4) . Further, the area of a cross section perpendicular to the direction of flow of the fluid is gradually increased from the connecting part in the fluid transfer flow passage (10) toward the outlet part. One or more air supply nozzles (15) for supplying combustion air are provided on the outer peripheral part of the nozzle (12).
