Abstract

Bei einem Speisewasser-Vorwärmer für eine Dampfkraftanlage (1) sind für eine besonders einfache Montage bei gleichzeitig geringem Platzbedarf erfindungsgemäß eine Anzahl von mit Anzapfdampf (A1, A2, A3) aus einer Dampfturbine (2) beheizbare Wärmetauschermodule (14, 16, 18) in einem gemeinsamen Gehäuse (20) angeordnet. Dabei sind die Wärmetauschermodule (14, 16, 18) speisewasserseitig in Reihe und anzapfdampfseitig parallel geschaltet.
