MULTI-STAGE COMPRESSOR AND METHOD FOR OPERATING A MULTI-STAGE COMPRESSOR |
摘要 |
A multi-stage compressor is described, comprising a rotor having a plurality of axially stacked impellers and a tie rod extending through the stacked impellers and holding the impellers together. A gas compression path extends from a compressor inlet to a compressor outlet and through the impellers. A flow channel is provided between the tie rod and the stacked impellers. The flow channel develops along at least a portion of the tie rod. Hot gas is diverted from the compression path and flows through the flow channel to heat the tie rod during startup of the compressor. |
