Abstract
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.
