    • A raw gas collection system for collecting raw gas from a plurality of aluminium smelting pots is equipped with a plurality of branch ducts (28d), each of which is arranged to channel a respective branch flow (38d) of raw gas from an aluminium smelting pot to a collection duct (26A), which is common to and shared by the branch ducts (28d). Each of said branch ducts (28d) is, near an outlet (52d) thereof, equipped with a curved section (50d) for aligning the branch flow (38d) with a flow direction of raw gas (27A) already present in the common collection duct (26A), and a constriction (54d) for accelerating the branch flow (38d) through the branch duct outlet (52d) into the common collection duct (26A). Furthermore, each of said branch ducts (28d) is equipped with a heat exchanger (40d) for removing heat from the respective branch flow (38d) of raw gas. The combined flow resistance of the constriction (54d) and the heat exchanger (40d) reduces the need for adjusting the respective branch flows (28d) using dampers, thereby reducing the power required to transport the raw gas.
    • 用于收集来自多个铝熔炼锅的原料气的原料气收集系统配备有多个分支管道(28d),每个分支管道被布置成引导来自铝熔炼罐的原料气的相应分支流(38d) 到分支管道(28d)共用的收集导管(26A)。 每个所述分支管道(28d)在其出口(52d)附近配备有弯曲部分(50d),用于使分支流(38d)与已经存在于公共收集器中的原料气体(27A)的流动方向对准 (26A)和用于加速通过分支管道出口(52d)进入公共收集管道(26A)的分支流(38d)的收缩部(54d)。 此外,每个所述分支管道(28d)装备有用于从原料气体的各个分支流(38d)去除热量的热交换器(40d)。 收缩部分(54d)和热交换器(40d)的组合流动阻力降低了使用阻尼器调节各个分支流(28d)的需要,从而减少了输送原料气所需的功率。

    • A heat exchanger transfers heat between first and second material streams. The heat exchanger includes a body portion including vent channels configured to pass the first material stream through the body portion. The body portion further includes feed channels configured to pass the second material stream through the body portion. The feed channels are spaced from and in thermal communication with the vent channels such that at least one of the first and second material streams transfer heat with another one of the first and second material streams. Each of the feed channels has an inlet having a crosssectional area with the cross-sectional area of the inlet of at least one of the feed channels different than the cross-sectional area of the inlet of another one of the feed channels for normalizing a flow rate of the second material stream through the feed channels.
    • 热交换器在第一和第二材料流之间传递热量。 热交换器包括主体部分,该主体部分包括被配置成使第一材料流通过主体部分的通气通道。 主体部分还包括被配置成使第二材料流通过主体部分的进给通道。 进料通道与排气通道间隔开并与通气通道热连通,使得第一和第二材料流中的至少一个与第一和第二材料流中的另一个流传递热量。 每个进料通道具有入口,其具有横截面积,其中至少一个进料通道的入口的横截面积不同于另一个进料通道的入口的横截面面积,用于使流动 通过进料通道的第二物料流的速率。
