据《Теплоэнергетика》2011年9月刊报道,为提高汽轮机发电机组的经济性,必须解决由于提高蒸汽初参数和增加汽轮机末级叶片长度引起的一系列技术和工艺问题。保证大功率汽轮机工作的可靠性和寿命,在很大程度上与提高运行中各种腐蚀耐受性有关,其中包括腐蚀破裂、磨蚀和水滴撞击浸蚀有关,这些都要求改进工质的质量、降低湿蒸汽级外缘的湿度、使用更完善的结 According to the September 2011 issue of “Теплоэнергетика”, a series of technical and technological problems due to the improvement of the initial parameters of steam and the increase of the final blade length of the steam turbine have to be solved in order to improve the economy of the steam turbine generator set. Ensuring the reliability and longevity of high-power steam turbine operations is largely associated with improving corrosion tolerance in operation, including corrosion cracking, abrasion and drop impact erosion, all of which require improved quality of the working fluid, Reduce the moisture level on the outer edge of the wet steam stage and use a more complete knot
