    • A forced-flow steam generator (1) having a surrounding wall (4) formed from steam generator pipes (2) which are welded in a gas-tight fashion and traversable by flow in the vertical direction, in which within the surrounding wall (4) there is arranged a passage collector (14) by means of which the outlet side of a first multiplicity of steam generator pipes (2) in parallel configuration is connected at the flow medium side to the inlet side of a second multiplicity, in series configuration with and downstream of the first multiplicity, of steam generator pipes (2) in parallel configuration, should have a particularly long service life and particularly low susceptibility to faults, independently of the operating state. For this purpose, the design parameters of the steam generator pipes (2) downstream of the passage collector (14) are selected such that the mean mass flow density in the steam generator pipes (16), in parallel configuration, of the surrounding wall (4) at full load of the steam generator (1) does not lie below 1200 kg/m2s.
    • 围墙一次通过蒸汽发生器(1)与从气密的,在垂直方向上,所述蒸汽发生器管形成,通过该(2)(4)在周围壁(4)的内侧具有焊接的贯通歧管(14),具有第一多个并联连接的蒸汽发生器管(2 )上并联连接的第二多个所述第一串行下游多个蒸汽发生器管(2)的出口侧连接的入口侧流动介质侧,应独立于操作状态的具有特别长的寿命和特别低的易感性的修复。 为了这个目的,所述通道收集器(14)的设计参数连接在蒸汽发生器管(2)的下游,被选择为使得在所述容纳(4)的并联连接的蒸汽发生器管(16)在蒸汽发生器(1)的全负荷时的平均质量流密度不/低于1200公斤M2S。
