JEA is soliciting Bids for a General Contractor for the replacement of Unit 2 and 3 Feedwater Heaters at Brandy Branch Generating Station (the Work ) JEA recently conducted a tube wall ultrasonic inspection (UT) and evidence of dew point corrosion was discovered in the feedwater heater (FWH) sections for HRSG Units 2 & 3. Many of the tubes have lost more than 50% of their original thickness. JEA has decided to replace the existing ASTM SA178A / SA106B carbon steel tube bundles, headers, and risers with OEM tube bundles. The project scope includes installing new feedwater heater sections, feedwater heater assemblies and risers per the original design. The FWH headers and associated piping will be reused to the fullest extent practical.

Any information not available from visible inspections may be obtained from non-destructive test methods approved by JEA. It will be the responsibility of the Contractor to coordinate inspections with JEA and contingent upon unit availability. The Contractor will be responsible for leaving the HRSG in the same condition as it was found prior to any inspections. The installation of the FW heaters will take place during 2023 spring outage.
