    • A boiler gas flow distribution fin includes an elongated flow distribution fin protruding from a back wall of a flow distribution channel into a hot gas flow path from a boiler combustion chamber. The flow distribution fin can include a leading segment with a leading ridge, a medial segment with a medial ridge, and a trailing segment with a trailing ridge. A gap between the fin ridges and a set of convective fins in an adjacent flue passageway segment can vary from a larger gap at the leading ridge to a smaller gap at the trailing ridge, transitioning along the medial ridge. The flow distribution fin can aid in directing a hot gas flow from a combustion chamber into the flue passageway segment, resulting in a substantially balanced mass flow rate through each of a series of flue passageway sections.
    • 锅炉气体流量分配翅片包括从流量分配通道的后壁突出到来自锅炉燃烧室的热气体流动通道中的细长的流动分配翅片。 流分配鳍片可以包括具有前脊的前段,具有中脊的中间段和具有后脊的后段。 翅片脊与相邻烟道通道段中的一组对流翅片之间的间隙可以从前缘脊处的较大间隙到后缘脊处的较小间隙变化,沿着内侧脊转变。 流量分配翅片有助于将热气体从燃烧室引导到烟道通道段中,从而通过一系列烟道通道段中的每一个产生基本平衡的质量流量。
