Performance Evaulation of Condensing System

Q1: Check/compare the temperatures and flow rates during operation versus the original HEI design datasheets......You did keep these, right ? Hopefully they were not thrown away by the previous political regime. Have accurate gauges.

Q2: Check the final vacuum achieved versus the design data sheets mentioned above. You should have in your possession expected vacuum levels versus cooling water temperature curves. ( Do you have any plant records at all ?)

Q3: Leakage testing of large steam surface condensers is commonly done by Helium Leak testing during operations. A wand is used and the entire condenser surface is "scanned". Where a leak occurs devices signal that there is heliem leaking. This is best done as a contracted service
