前言火力发电机组中的受压零部件,在高温负载下常常会产生蠕变破坏事故,更常见于锅炉管子中。如能正确地分析锅炉管子的使用寿命,提高高温过热器管的可靠性,则能进一步提高机组整体的经济性与可靠性。在此我们试图以经长期使用的过热器管
Preface Pressure components in thermal power units often experience creep damage at high temperatures, more commonly in boiler tubes. If you can correctly analyze the service life of boiler tubes and improve the reliability of high temperature superheater tubes, you can further improve the overall economy and reliability of the unit. Here we try to use the long-term superheater tube
