Back end valves: history and modifications, status report, June 1983

Technical Report ·
OSTI ID:6609692
At the Grimethorpe Experimental Facility the valves which control the combustor freeboard pressure are known as the back end valves. They are situated downstream of the main heat exchanger. They are required to work under adverse conditions and their operation has not been without problems. The report provides a description of the valves and a history of their operation and modifications from December 1980 to April 1983. Considerable erosion and control problems were experienced during 1981, however, operational and mechanical modifications have now been made which have greatly improved the reliability of the valves.
