General components experience at the Grimethorpe PFBC (Pressurised Fluidised Bed Combustion) Facility during Test Series A2
Technical Report
·
OSTI ID:6202082
Test Series A2 was carried out at the Grimethorpe Pressurized Fluidized Bed Combustion (PFBC) Establishment as part of the British Coal/CEGB Joint Programme on PFBC between March and November 1987. Additional funds for the Test Series were obtained from the US Department of Energy, EPRI and the UK Department of Energy. At the end of the Test Series a comprehensive inspection took place. The report describes the results of this inspection, and also analyses component failures during operation. Particular attention is given to the dry and wet fuel feed problems (where the performance of the various pumps gave rise to problems), hot gas ducting, and the steam water circuit. Improvements are reported in the performance of high temperature ash control valves. The performance of an EPRI HTHP filter unit and the in-bed tube bank are not specifically covered by this report. The report concludes that, from the components experience in Test Series A2, the problems experienced which would be applicable to commercial PFBC systems can be overcome by appropriate attention to the details of design. 15 refs., 53 figs., 7 tabs.
