Abstract:

Wright-Patterson AFB WPAFB tasked the U.S. Army Construction Engineering Research Laboratory CERL to investigate the best way to resolve the problem of incorrect safety valves installed on fired pressure vessels in high temperature hot water HTHW generators. Additionally, WPAFB requested help in controlling system pressure in the HTHW system during large load swings, and guidance on how to pipe expansion tank discharge to a blowoff tank. CERL researchers visited the site, inspected the system, researched relevant specifications, and recommended that 1 the screen interface for the computerized plant data recording system at Plant 1240 be modified to trend plant pressure and N2 expansion tank level to help troubleshoot pressure control problems, 2 two V safety valves be installed on each HTHW unit, and 3 the blowoff valve, piping, and tank configuration be modified to eliminate water hammer.
