超超临界机组设计技术集成化发展探讨

Integrated Design Technology Development of Ultra Supercritical Unit

通过对我国超超临界火电机组发展现状及与国外先进火电机组设计技术方面主要差距的研究,提出了国际上超超临界机组设计技术的发展趋势是设计技术集成化发展。分析了日本和德国超超临界机组设计技术集成的主要工艺,汇总了我国超超临界机组设计技术集成化发展可采用的技术和所面临的主要问题,并对我国未来超超临界机组设计技术集成化如何发展提出了建议。

This paper analyzes the status of Chinese ultra-supercritical coal-fired power unit（USC unit）and its gap with the design technologies of advanced coal-fired units abroad,and especially points out that the integrated design technology is the development trend for international USC units.The main process of integrated design technology applied in Japan and German is also investigated,as well as the feasible technology and main problems for application of this technology in Chinese USC unit.In addition,proposals are made for advancement of integrated design technology of USC units in China.
