Method for evaluating the technical state of boilers and piping in thermal power plants

  • Published:
Power Technology and Engineering Aims and scope

An approach for evaluating the current technical state of thermal equipment in thermal power plants is discussed. A system of parameters and corresponding criteria are developed for the technical state of groups of essential components of boilers and piping. Ascale for evaluation of safety factors is proposed in terms of the relationship between state parameters and the corresponding criteria. Analytic expressions are given for an approximate evaluation of the maximum lifetime limit for operation of an object in terms of an integral safety factor and an evaluation of this type is illustrated for the case of the live steam pipeline in a 300-MW unit. An algorithm is set up for actions to be taken by equipment owners in organizing monitoring of the technical state of the equipment.
