Die vorliegende Erfindung betrifft einen Wärmetauscher gemäss dem Oberbegriff des unabhängigen Patentanspruchs I . The present invention relates to a heat exchanger according to the preamble of independent claim I.
Wärmetauscher mit mehreren über einen vorgegebenen Längenbereich parallel verlaufenden Wärmetauscherrohren werden typischerweise in Verbrennungsanlagen, insbesondere Kehricht- bzw. Müllverbrennungsanlagen, eingesetzt, wo sie in einem oder mehreren Zügen der Verbrennungsanlage meist frei hängend angeordnet sind und zur Kühlung der Rauchgase dienen. Die dabei gewonnene Energie wird üblicherweise zur Dampferzeugung bzw. Dampfüberhitzung ausgenutzt. Heat exchangers with a plurality of heat exchanger tubes extending in parallel over a given length range are typically used in incineration plants, in particular waste incineration plants, where they are usually arranged suspended freely in one or more passes of the incineration plant and serve to cool the flue gases. The energy gained is usually used to generate steam or steam overheating.
Ein gattungsgemässer Wärmetauscher für Vcrbrennungsanlagen ist in der A generic heat exchanger for Vcrbrennungsanlagen is in the
EP 2 754 961 A2 beschrieben. Bei diesem sogenannten hinterlüfteten Wärmetauscher erfolgt die Luftzufuhr bzw. allgemeiner die Zufuhr von Schutzgas in einen  EP 2 754 961 A2. In this so-called ventilated heat exchanger, the air supply or more generally the supply of protective gas in one
Zwischenraum zwischen den Wärmetauscherrohren und deren Schutzverkleidung durch spezielle Gasrohre, die im Wesentlichen parallel zu den Wärmetauscherrohren verlaufen. Die aus Keramik oder vorzugsweise Metall bestehenden Gasrohre weisen mindestens eine Austrittsöffnung, vorzugsweise mehrere über ihre Länge verteilt angeordnete Austrittsöffnungen, auf, durch welche die Luft bzw. das Schutzgas an der oder den gewünschten Stellen entlang der Wärmetauscherrohre des  Interspace between the heat exchanger tubes and their protective cover by special gas pipes, which extend substantially parallel to the heat exchanger tubes. The ceramic or preferably metal existing gas pipes have at least one outlet opening, preferably a plurality of distributed over its length arranged outlet openings, through which the air or the inert gas at or desired locations along the heat exchanger tubes of the
Wärmetauschers in den Zwischenraum zwischen den Wärmetauscherrohren und der Schutzverkleidung austritt. Die Luft- bzw. Gaszufuhr in den Zwischenraum mittels spezieller Gasrohre ist konstruktiv relativ aufwändig. Ausserdem ist es mit dieser Technologie praktisch kaum möglich, bestehende Wärmetauscher ohne Hinterlüftung nachträglich mit einer Hinterlüftung auszurüsten. Durch die vorliegende Erfindung soll daher ein Wärmetauscher der gattungsgemässen Art hinsichtlich der Schutzgaszufuhr vereinfacht und verbessert werden. Die der Erfindung zugrundeliegende Aufgabe wird erfmdungsgemäss durch einen Wärmetauscher gelöst, wie er durch die Merkmale des unabhängigen Patentanspruchs 1 spezifiziert ist, bzw. durch eine Verbrennungsanlage mit einem solchen Heat exchanger in the space between the heat exchanger tubes and the protective panel emerges. The air or gas supply into the gap by means of special gas pipes is structurally relatively complex. Moreover, it is virtually impossible with this technology to retrofit existing heat exchangers without rear ventilation with a rear ventilation. By the present invention, therefore, a heat exchanger of the generic type is to be simplified and improved with respect to the protective gas. The problem underlying the invention is solved according to the invention by a heat exchanger, as specified by the features of independent claim 1, or by an incinerator with such
Wärmetauscher gemäss dem unabhängigen Patentanspruch 10. Weitere vorteilhafte Aspekte ergeben sich aus den Merkmalen der abhängigen Patentansprüche. Heat exchanger according to the independent claim 10. Further advantageous aspects emerge from the features of the dependent claims.

Vorzugsweise münden die Gasauslassöffnungen zu beiden Seiten der Rohrwand in den mindestens einen Zwischenraum aus. Dies fuhrt beidseits der Rohrwand zu einer guten Hinterlüftung. Bei einer vorteilhaften Ausführungsvariante besteht der Gasverteilkasten im The gas outlet openings preferably open out on both sides of the tube wall into the at least one intermediate space. This leads on both sides of the pipe wall to a good rear ventilation. In an advantageous embodiment, the gas distribution box is in

Ein solcher Gasverteilkasten ist relativ kostengünstig und einfach herzustellen und zu montieren. Essentially of a refractory material, preferably ceramic material. In an alternative advantageous embodiment, the gas distribution box is made of steel. Such a gas distribution box is relatively inexpensive and easy to manufacture and assemble.
Mit Vorteil ist der Gasverteilkasten bezüglich der Einbaulage des Wärmetauschers am unteren Ende der Schutzverkleidung angeordnet. Dadurch kann eine optimale Hinterlüftung mit einem Schutzgasstrom von unten nach oben erreicht werden. Advantageously, the gas distribution box is arranged with respect to the installation position of the heat exchanger at the lower end of the protective cover. This allows optimal ventilation with a protective gas flow from bottom to top can be achieved.
