超超临界二次再热汽轮机发展综述

Development of Ultra-supercritical Double-reheat Steam Turbine

文章概述了汽轮机二次再热技术的发展历程,当前我国超超临界二次再热汽轮机技术研发情况,并重点介绍了我国首台超超临界二次再热汽轮机技术特点及运行情况,对未来二次再热汽轮机技术发展方向和典型机型进行了探讨。

This paper introduces the evolution of double-reheat turbine technology, the development of the ultra-supercritical doublereheat turbine technology in China,and mainly introduces the technical charateristic and operation conditions of the first ultra-supercritical double-reheat turbine unit made by DTC in China. The new development direction and typical models of the double-reheat steam turbine designed by DTC is discussed in this paper.
