Abstract

Beschrieben wird eine Vorrichtung zur Reinigung oxidierter oder korrodierter Bauteile (26), insbesondere von Heissgasen ausgesetzten Gasturbinenkomponenten, in Gegenwart eines halogenhaltigen Gases, mit einem kessel- oder zylinderförmig ausgebildeten Reinigungsreaktor, in den mittel- oder unmittelbar eine Speiseleitung mündet, die über eine Durchflussregeleinrichtung mit einem das halogenhaltige Gas bevorratenden Gasreservoir verbunden ist und in den eine Vorrichtung zur Gasverteilung integriert ist.
Die Erfindung zeichnet sich dadurch aus, dass die Durchflussregeleinrichtung in Abfolge längs der Durchströmungsrichtung des die Speiseleitung durchströmenden halogenhaltigen Gases ein Gasmengenregelventil (5), eine Wärmetauschereinheit (9) sowie eine Gasmengenmesseinheit (6) besitzt. Ferner wird eine Gasverteilung im Reaktor beschrieben, die das halogenhaltige Gas direkt zu den zu reinigenden Komponenten leitet.
