Assessment of Reliability and Technical Risks in the Operation of Heat Engineering Units

Abstract

A method for assessing technical risks arising during the operation of heat engineering units is presented. Risk assessment is based on the data on the residual life of the unit’s lining and an evaluation of the severity of the consequences of an accident. To obtain primary data when assessing the residual life, an instrument method is used that allows continuous monitoring of the thermal state of the lining. Thermomechanical stresses exceeding the ultimate strength of the material are shown to be the determining destruction factor. These stresses are calculated according to the developed scheme based on numerical methods.
