TURBINE PROTECTION – TWO PHASE FLOW REGIMES
During the commissioning of an Eskom Power Station Unit, severe dynamic movement occurred on both lines to the deaerator. The identified lines were taken out of service and the cause was investigated. After initial investigations it was concluded that the lines were too flexible. The CAESAR1 model was revisited and additional supports were installed. This, however, did not solve the problem. The problem thus had to be process-related.
