Mathematical Model of Large Axial-Flow Compressor And Its Use in On-line Monitoring1

摘要

This paper expounds the practical performance of large axial-flow compressors used as the factory is power recovery train in the oil refinery catalytic cracking equipment. A common mathematical performance model is set up with computer assistance. Then its application in operating compressors on-line monitoring and surge prognosis is further studied. It is shown by study that the model is rational and its application is feasible. It is obviously significant for improving the safety and economy of the pirating compressors.
