Abstract

Die Erfindung betrifft einen Fliehkraftabscheider (1) als Rückführzyklon für eine Wirbelschichtfeuerung. Der Fliehkraftabscheider (1) umfasst wenigstens ein Gehäuse (2), welches eine Wirbelkammer (5) bildet. Das Gehäuse umfasst wenigstens einen tangentialen Einlauf und einen in Einbaulage unteren Austrag (4) für die im Zentrifugalfeld abgeschiedenen schweren Bestandteile und einen bezogen auf die Einbaulage oberen, eine Gehäusedecke (6) durchsetzenden Austrag, welcher ein sich in das Gehäuse (2) erstreckendes Tauchrohr (9) umfasst. Der Fliehkraftabscheider gemäß der Erfindung zeichnet sich dadurch aus, dass das Tauchrohr (9) an die der Wirbelkammer (5) zugekehrte Seite der Gehäusedecke (6) angeschlossen ist.

The invention relates to a centrifugal separator (1) as a recycling cyclone for fluidized bed combustion. The centrifugal separator (1) comprises at least one housing (2), which forms a vortex chamber (5). The housing comprises at least one tangential inlet and a lower outlet (4) in the installation position for the heavy components deposited in the centrifugal field and a discharge passing through a housing cover (6) relative to the installation position, which is a dip tube extending into the housing (2) (9). The centrifugal separator according to the invention is characterized in that the dip tube (9) to the vortex chamber (5) facing side of the housing cover (6) is connected.
