Turbo compressor supported only by its inlet and outlet flanges

Abstract

The invention concerns a radial turbo compressor (TCO) including at least one impeller (IP) at least one casing (CS), the impeller (IP) is rotatable about an axis (X), the casing (CS) comprises an inlet (IL) upstream of the impeller (IP), the inlet (IL) comprising an inlet flange (IF) to be mounted to a process gas pipe (PGP), the casing (CS) comprises an outlet (OL) down-stream of the impeller (IP) comprising an outlet flange (OF), the casing (CS) comprises an outlet volute (VL) extending about the axis (X) downstream of the impeller (IP) and upstream of the outlet (OL), and the radial turbo compressor (TCO) comprises a drive unit (DRU) driving the impeller (IP) and being mounted to the casing (CS). In order to simplify exhaust gas quality improvement the invention proposes that the casing (CS) is exclusively supported by the inlet flange (IF) and the outlet flange (OF), the casing (CS) comprises a drive unit flange (DRF), the drive unit (DRU) comprises a fixation flange (FF), the drive unit flange (DRF) and the fixation flange (FF) are fixedly connected to each other by fixation elements (FE), the drive unit (DRU) being exclusively supported by the fixation flange (FF). Further, the invention deals with an arrangement (AR) comprising such a turbo compressor (TCO).
