BI-METALLIC TUBE STEAM GENERATOR FOR APPR-1. VOLUME I. SPECIFICATIONS

Technical Report ·
DOI:https://doi.org/10.2172/4335131· OSTI ID:4335131
These three volumes were issued separately, but are cataloged as a unit. Complete specifications and drawings are given for a bi-metallic tube steam generator replacement at Fort Belvoir, Virginia. Physical size limitations, shell side water volume, limitation, type of exchanger, materials of construction, conditions of service, required performance, and weight limitation are included. Procedures are outlined for removing the existing steam generator at APPR-1 and installing a new unit. The effect of replacing the present Type 304 stainless steel boiler with a bi-metallic tube steam generator was analyzed from the standpoint of chemical operations at the plant. Corrosion control procedures were established to prevent formation of deposits, scale, or pits on the boiler tubes as well as to protect other parts of the system. Water treatment procedures were revised to insure satisfactory operation of the boiler by removing dissolved oxygen, minimizing hideout and carryover, neutraliziog carbon dioxide, and maintaining proper pH. The chemical feed system was revised to eliminate problems encountered with the present equipment and to obtain the reliability required with a less corrosion resistant boiler material. Operating; procedures were reviewed to reflect the above and to switch emphasis from chloride to oxygen control in the make-up, storage, and condensate systems. (auth)
