    • A temperature control system, particularly for low load conditions, is described including a by-pass line (132) with a by-pass control valve (133) branching off a live steam circuit (13) to a first steam turbine (14) in a sequence of at least two steam turbines (14, 18), with a steam exit line of the first turbine merging with the by-pass line into the inlet of a reheater (16) heated by a steam generator (10) and connected to a second steam turbine (18) of the sequence of at least two steam turbines, and having a steam mixing chamber (151) at or after the point of merging and before the inlet into the reheater. The desired temperature is set by controlling the mass flow through the by-pass line and/or the first turbine.
    • 描述了一种特别用于低负载条件的温度控制系统,其包括旁路管线(132),旁路管线(132)与旁通控制阀(133)分离出带电蒸汽回路(13)到第一汽轮机(14) 至少两个蒸汽涡轮机(14,18)的序列,其中第一涡轮机的蒸汽出口管线与旁路管路合并到由蒸汽发生器(10)加热的再加热器(16)的入口中,并连接到 至少两个蒸汽涡轮机的序列的第二蒸汽轮机(18),并且在合并点之后或之后以及在进入再热器的入口之前具有蒸汽混合室(151)。 通过控制通过旁路线路和/或第一涡轮机的质量流量来设定期望的温度。
