Train Performance - Evaluation and Monitoring by Torque Meter Applications and Process Gas Compressor / Steam Turbine Train Fouling and Washing Mitigation
MetadataShow full item record
The systematic monitoring and evaluation of turbomachinery is an important diagnostic tool in the execution of a long-term maintenance plan as well as the prevention of unexpected outages due to machinery breakdown. This paper introduces the typical causes of performance deterioration in compressors and steam turbines and the phenomena related to their causes. In addition, this paper also introduces how to evaluate performance, based on site monitoring techniques are explained by combining typical evaluation results with torque measurement and maximum power limit control. Evaluation of these results can determine if deterioration in performance, caused by a change in the internal flow conditions, has occurred. Finally, typical results from on-line washing techniques for compressors and steam turbines will be introduced and the power recovery rate after on-line washing, measured by the torque meter, will be discussed.
