Bei Anordnung zum Schutz von Rohrabschnitten von in einem Gaskanal (1) angeordneten schottenartigen Heizflächen (6) gegen Verschleiß durch mit Feststoffteilchen beladenen Gasen ist vorgeschlagen, daß das Verschleißschutzelement (10) längs seiner Erstreckungsrichtung ohne vorherige Lösung einer festen Verbindung zu den zu schützenden Rohrabschnitten (8; 9) aus dem Gaskanal (1) herausziehbar ist. Das Verschleißschutzelement kann in Form eines drehbaren Deflektors (10) die Endbögen von Rohren oder in Form eines Vollprofils geradlinige Rohrabschnitte schützen. In the case of an arrangement for protecting tube sections of plate-like heating surfaces (6) in a gas duct (1) against wear caused by gases charged with solid particles it is proposed that the anti- wear element (10) can be extracted from the gas duct (1) along the direction in which it extends without prior detachment of a fixed connection to the tube sections (8; 9) to be protected. In the form of a rotatable deflector (10), the anti-wear element can protect the terminal bends of pipes, or in the form of a complete section straight tube sections. ……
