摘要： In a heater for a liquefied stream, a first heat transfer zone has a box stretching longitudinally along an axis. A first heat transfer surface is arranged inside the box, across which a first indirect heat exchanging contact is established between a liquefied stream that is to be heated and a heat transfer fluid. A second heat transfer zone is located gravitationally lower and includes a second heat transfer surface across which the heat transfer fluid is brought in a second indirect heat exchanging contact with the ambient. A downcomer fluidly connects the first heat transfer zone with the second heat transfer zone and has a first transverse portion and a first downward portion that are fluidly connected to each other via a connecting elbow portion. The connecting elbow portion, when viewed in a vertical projection on a horizontal plane, is located external to the box compared to the axis.

摘要翻译： 在用于液化流的加热器中，第一传热区具有沿轴线纵向延伸的箱体。 第一传热表面设置在箱体的内部，在待加热的液化物流与传热流体之间建立起第一间接热交换接触。 第二传热区域重力地位于下方，并且包括第二传热表面，传热流体通过该第二传热表面与环境进行第二间接热交换接触。 降液管将第一传热区域与第二传热区域流体连接，并且具有通过连接弯头部分彼此流体连接的第一横向部分和第一向下部分。 连接弯头部分，当在水平面上的垂直投影中观察时，与轴相比位于箱的外部。
