Abstract

Um bei einem Rohrboden (100) zur Aufnahme von Rohren eines Nachschaltwärmetauschers für einen Heizkessel, insbesondere einen Brennwertkessel, zum Kühlen und Kondensieren von Abgasen eines Brenners des Heizkessels, das Auftreten von Materialspannungen aufgrund von während des Betriebes auftretender und auf den Rohrboden (100) wirkender Belastungen, bspw. kinetischer und/oder thermischer Art, zu verringern, wird vorgeschlagen, dass der Rohrboden (100) mehrschichtig ausgebildet ist, wobei die einzelnen Schichten (11,12,13,15,16) miteinander verbunden sind, und wobei wenigstens zwei Schichten (11,12,13,16) aus Metall bestehen.

In order for a tube plate (100) for receiving tubes of a Nachschaltwärmetauschers for a boiler, in particular a condensing boiler, for cooling and condensing exhaust gases of a burner of the boiler, the occurrence of material stresses due to occurring during operation and on the tubesheet (100) acting To reduce loads, such as kinetic and / or thermal type, it is proposed that the tube sheet (100) is formed multi-layered, wherein the individual layers (11,12,13,15,16) are interconnected, and wherein at least two Layers (11,12,13,16) consist of metal.
