摘要
二次再热系统比一次再热在机组效率和煤耗上优势明显,针对火力发电厂二次再热超超临界机组,介绍了国内外的技术发展和应用情况,通过分析二次再热超超临界机组设计的主要技术难点,进一步探讨了二次再热机组蒸汽参数选择、锅炉设计、汽轮机及热力系统设计的思路。
Double reheat cycle has a significant advantage to one reheat cycle at unit elnciency and coal consumption. Domestic and international technic development of ultra - supercritical unit with double reheat cycles is discussed. The selection of steam parameter, design of boiler, design of tur- bine and thermal system of ultra - supercritical unit with double reheat cycles are proposed by analy- zing the main technical difficulties.
