Multistage compressor and method for operating a multistage compressor

Multistage compressor and method for operating a multistage compressor

A multi-stage compressor (10) is described, comprising a rotor (11) having a plurality of axially stacked impellers (12; 12B, 12) and a tie rod (14) extending through the stacked impellers and holding the impellers together. A gas compression path (P) extends from a compressor inlet to a compressor...

description A multi-stage compressor (10) is described, comprising a rotor (11) having a plurality of axially stacked impellers (12; 12B, 12) and a tie rod (14) extending through the stacked impellers and holding the impellers together. A gas compression path (P) extends from a compressor inlet to a compressor outlet and through the impellers. A flow channel (17) is provided between the tie rod (14) and the stacked impellers (12, 12A, 12B). The flow channel develops along at least a portion of the tie rod (14). Hot gas is diverted from the compression path (P) and flows through the flow channel to heat the tie rod during startup of the compressor.
