Abstract

Die Erfindung betrifft eine Anordnung zur Verhinderung der Taupunktkorrosion im Lufteintrittsbereich eines rauchgasbeheizten Roehrenluftvorwaermers, wobei Rohre in einem Rohrende fixiert und die ueber den Rohrboden herausragenden Rohrenden mit einer Waermeisolierung versehen sind. Zur Anhebung der Temperaturen des Rohrbodens und der Rohre im Lufteintrittsbereich ist eine mit Bohrungen versehene Waermedaemmatte auf die Rohrenden aufgesteckt und durch in die Rohre eingesteckte, mit einem Bund versehene Federrohrhuelsen fixiert, wobei die Federrohrhuelsen eine im Bereich des Rohrbodens ausgebildete Einziehung aufweisen.The invention relates to an arrangement for preventing dew point corrosion in the air inlet region of a flue gas-heated Roehrenluftvorwaermers, wherein pipes fixed in a pipe end and the projecting over the tube sheet tube ends are provided with a heat insulation. To increase the temperatures of the tube plate and the tubes in the air inlet area provided with holes heat transfer mat is attached to the pipe ends and fixed by inserted into the pipes, provided with a collar Federrohrhuelsen, wherein the Federrohrhuelsen have formed in the region of the tube bottom confiscation.
