摘要

从1956年世界上第一台二次再热机组在西德的诞生到世界上效率最高的二次再热机组在中国华能莱芜发电有限公司的投运

二次再热技术经历了半个多世纪的发展。目前

世界范围内已投运的58台二次再热机组中

我国的6台高参数超超临界二次再热机组

无论是蒸汽参数还是机组效率均已达到世界先进水平。经过近几年的探索

我国逐步掌握了完整、成熟的二次再热技术

涵盖系统设计、锅炉、汽轮机、控制等各个方面。结合二次再热机组的技术特点和目前我国煤电发展的趋势

未来二次再热机组在我国的发展应该以效率、经济性为主

同时兼顾灵活性。

Abstract

The double-reheat power generation technology has a development history of more than half a century

from the first double-reheat thermal power unit commissioned in West Germany in 1956 to the most advanced double-reheat thermal power unit put into operation in Huaneng Laiwu Power Plant

China. According to incomplete statistics

there have been at least 58 double-reheat thermal power units put into operation worldwide. Among which the 6 double-reheat thermal power units commissioned in China are designed with excellent steam parameters and generating efficiencies

which have reached a world-class level. Based on the development in recent years

a set of complete and mature double-reheat technology has been mastered by sci-tech personnels in China

including system design

boiler

turbine

control technology

and so on. Considering the characteristics of doublereheat technology and the development trend of thermal power plants in China

enhancing efficiency and economic viability will be the primary objectives. Besides

considering the flexibility will also be an important target for double-reheat technology.
