Research on Reliability Prognostication Models of Boiler Parts

By associating the theory of reliability prognosis with the theories of streagth and life expectancy, the paper broaches a new method for reliability prognostication of boiler parts. The paper analyses the numerous factors that affect the failure of boilers and gives the physical import of the various factors that follow weibull's distribution, suggests a falure model of boiler parts which takes into consideration the simultaneous action of various factors. The paper also includes a suggestive method for prognosticating, from the point of view of reliability, the operation reliability of boiler parts.
