    Abstract: A burner is arranged axially of a burner throat on a furnace wall and includes a nozzle body housed in a wind box and with a secondary air adjuster on a leading end of the nozzle body. The adjuster includes an end plate for defining together with a near-furnace side surface of the wind box a cylindrical space opened in an outer circumference thereof, a slide damper axially slidable for surrounding the cylindrical space, air vanes arranged at predetermined intervals and circumferentially of the cylindrical space for swirling a secondary air and drive means and for slide movement of the slide damper.

    Abstract: A solid fuel burner using a low oxygen concentration gas as a transporting gas of a low grade solid fuel such as brown coal or the like and a combustion method using the solid fuel burner are provided. The solid fuel burner comprises a means for accelerating ignition of the fuel and a means for preventing slugging caused by combustion ash from occurring. Mixing of fuel and air inside a fuel nozzle 11 is accelerated by that an additional air nozzle 12 and a separator 35 for separating a flow passage are arranged in the fuel nozzle 11, and the exit of the additional air nozzle 12 is set at a position so as to overlap with the separator 35 when seeing from a direction perpendicular to a burner axis, and additional air is ejected in a direction nearly perpendicular to a flow direction of a fuel jet flowing through the fuel nozzle 11. An amount of air from the additional air nozzle 12 is varied corresponding to a combustion load. By increasing the amount of air from the additional air nozzle 12 at a low load operation, an oxygen concentration of a circulation flow 19 formed in a downstream portion outside the exit of the fuel nozzle 11 is increased to stably burn the fuel. By decreasing the amount of air from the additional air nozzle 12 at a high load operation, a flame is formed at a position distant from the fuel nozzle 11 to suppress radiant heat received by structures of the solid fuel burner and walls of the furnace.

    Abstract: An improved pulverized coal burner that reduces the formation of nitrogen oxides. The coal burner includes fuel splitters that separate a mixture of primary air and coal into a plurality of streams while the mixture is discharged through a diffuser having a plurality of partially open areas and a plurality of blocked areas. After passing through the diffuser, the plurality of streams are discharged into a furnace to be burned. The plurality of partially open areas and blocked areas are created by removing sections of the diffuser and replacing the removed sections with fuel splitters. Creation of these discrete streams delays mixing with secondary air. Because primary air is supplied in sub-stoichiometric quantities, the coal in these split streams will be burned under fuel-rich conditions for the first 100 to 200 milliseconds of combustion, until the delayed mixing of secondary air occurs. Combustion in a fuel-rich environment retards formation of nitrogen oxides in two ways. First, nitrogen that is part of the volatile matter that is evolved during the early stages of combustion will tend to form molecular nitrogen rather than react with oxygen to form nitrogen oxides. Second, an oxygen deficiency will reduce formation of nitrogen oxides from atmospheric nitrogen.

    Abstract translation: 一种改进的粉煤燃烧器，可减少氮氧化物的形成。 煤燃烧器包括燃料分配器，其将一次空气和煤的混合物分离成多个流，同时通过具有多个部分开放区域和多个阻塞区域的扩散器排出混合物。 在通过扩散器之后，将多个流排出到待燃烧的炉中。 通过去除扩散器的部分并且用燃料分离器代替去除的部分来产生多个部分开放区域和阻塞区域。 这些离散流的创建延迟了与二次空气的混合。 由于一次空气以亚化学计量的方式供应，这些分流中的煤将在富燃料条件下燃烧第一个100至200毫秒的燃烧，直到发生二次空气的延迟混合。 在富含燃料的环境中的燃烧有两种方式阻碍了氮氧化物的形成。 首先，作为在燃烧的早期阶段演化的挥发性物质的一部分的氮将倾向于形成分子氮而不是与氧反应形成氮氧化物。 第二，缺氧会减少氮氧化物从大气氮的形成。

    Abstract: A system includes a feed injector that may supply a feedstock to a gasifier. The feed injector includes one or more conduits extending toward a tip portion having an outlet, cooling coil coupled to the tip portion, and a protective shell including a first protective shell portion coupled to a second protective shell portion. The protective shell surrounds the tip portion and at least portions of the one or more conduits and the cooling coil. The feed injector also includes one or more mounting structures disposed along an outer perimeter of the feed injector. The one or more mounting structures may facilitate coupling of the first protective shell portion, the second protective shell portion, and the feed injector.
