    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 spiders. 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 ears 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. Two variations of bypass conduits are disclosed that allow a portion of the mixture of primary air and coal to bypass the diffuser and discharge into the furnace.

    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用燃料蜘蛛代替去除的部分来创建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，作为挥发性物质的一部分的氮在燃烧期间演化，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。 公开了旁路管道的两种变型，其允许一次空气和煤的混合物的一部分绕过扩散器并排放到炉中。
