A Study of Boiler Water Wall Leakage and Boiler Expert System for Fault Diagnosis

The safety and economy of boilers in power plant have been influenced by water wall leakage. 5 kinds,16 types of water wall fault have been detailed presented. On the basis of water wall experiments, the authors carefully analyzed the cause of transverse crackle. In order to establish boiler expert system of fault diagnosis, the authors employed object oriented methodology to carry out detailed analysis on boiler pipe fault diagnostic problems. The studies of rule based knowledge representation for diagnosis and corresponding strategy for knowledge acquisition and diagnostic inferences with C language using proper data structures were made. A software system boiler expert system of fault diagnosis was realized, which was composed using Borland C ++ for windows.
