High Pressure Boiler Feedwater Heater Replacement

Project Overview

The project involved the demolition and removal of an existing feedwater heater and the placement and installation of a new feedwater heater.  The replacement feedwater heater was larger diameter and heavier than the existing feedwater heater.  This required  structural modifications to the support framing along with the operating room floor.  Temporary floor reinforcement was required for staging the installation of the replacement feedwater heater.  The existing piping had to be restrained once is it was disconnected from the existing feedwater due to cold spring being designed into the piping.  Piping modifications were required because of the larger diameter feedwater heater.  Also, in order to improve operation of the feedwater heater a new alternate drain line was designed.  Pipe stress analysis was performed on the new piping and feedwater heater nozzles using CAESAR II software.  Various instruments had to be replaced or relocated due to the age of the instruments and the larger feedwater heater being installed.  The deliverables included both demolition and construction drawings for the structural steel modifications and details, piping layout and details, pipe stress analysis, instrument location plans, wiring diagrams and bills of material.
