主 题：supercritical CFB water supply cut off electricity failure accident analysis
摘 要：Controversies still exist over the necessity of equipping with an emergency water supply system in the supercritical circulating fluidized bed/CFB *** resolve the dispute,research on the safety of the heating surfaces in the supercritical CFB boiler during the electricity failure accident under the assumption of not putting the emergency water supply system into use must be ***,due to the low incidence rate of this accident,no relevant data have been reported *** provide useful data for the related research,a breakdown accident of the main feed water pump that happened in a 350 MW supercritical CFB boiler was introduced in this *** analysis of the physical processes in both the furnace and water side of the boiler during this accident was *** the discussion on the similarities and discrepancies between the two accidents was carried *** was found out that with appropriate handling,the data collected in two periods of the breakdown accident of the main feed water pump can provide a reference for the verification of the prediction model of the electricity failure ***,a preliminary prediction model was established as the first step of the verification work.
