Study On The Life Management Of The Supercritical Generating Units' Heating Surface Pipe

At present in the world in life assessment management system, with the United States EPRI as the representative for high temperature and high pressure components of creep and fatigue life management research has been more perfect, the United States EPRI established detection and diagnostic center (M&D), which is responsible for the material life of equipment research, development and demonstration power plant operation and maintenance for the detection and diagnosis technology, including diagnostic system implementation improvement, comprehensive detection and diagnosis system for the application of computer network, diagnosis and predictive repair procedure of optimal maintenance, software development, technical training, diagnosis. Another German MPA development ALIAS in EC countries application of good. For ultra supercritical units and metal new material life management technology research and development platform and application has not yet been established.For ultra supercritical unit heating surface tube operating experience, service performance data is not sufficient, life assessment methods do not mature, domestic materials of large quantities of use and other circumstances, be developed as soon as possible in ultra supercritical unit heating surface tube life management and platform research and development work, to ultra supercritical unit heating surface tube supervise prevention control of timely, effective safety management.According to the demand of research and the system function analysis, to determine the" ultra supercritical unit life management platform" development goals:will power plant heating surface tube basic information, operation information, maintenance information, life assessment and integrated into the" life management platform", in the unit of rapid scientific and regular overhaul of components and materials safety assessment and life assessment for equipment maintenance, decision making, and the safety supervision and management to provide technical basis. According to the demand investigation and analysis for the system function, write" ultra supercritical unit heating surface tube life management system functional requirements specification". The" ultra supercritical unit heating surface tube life management platform" development goals:the heating surface tube basic information, operation information, maintenance information, life assessment and integrated into the" heating surface tube life management platform", in the unit of rapid scientific and regular maintenance of parts and materials for safety evaluation and life evaluation for equipment maintenance, decision making, and the safety supervision and management to provide technical basis.On the basis of ultra supercritical unit heating surface tube life management system functional requirements specification", elaborated the user demand the design scheme, the" ultra supercritical unit heating surface tube life management platform " overall architecture, database structure and the interface is analyzed, designed and defined, the system data structure and software structure, gives the system interface definitions and the function of each software module definition.On the maturation of ultra supercritical boiler tube life calculation method as the basis, completed the" ultra supercritical unit life management platform" system functional requirements specifications, outline design and database design of compiling.
