摘要
神华(福州)罗源湾港电有限公司一期工程建设2×1 000 MW火力发电机组,汽轮发电机组设计热耗为7 202 k J/k W·h。对该汽轮机进行了介绍,并与目前国内其他型号1 000 MW汽轮机进行了对比,对于汽轮机应用的关键技术如防止汽流激振,超速保护及高、低压缸结构进行了分析,阐明了超高效汽轮机在安全性和经济性上的优势,提出了今后还需对轴系支撑方式和回热系统等方面进行改进。
There are two 1 000-MW units installed in the first phase project of Shenhua （Fuzhou） Luoyuan Bay Port ＆ Power Co., Ltd. with the designed heat rate of 7 202 kJ/（kW ·h）. In this paper, the steam turbines of this power plant are introduced and compared with the domestic 1000-MW steam turbines of some other different types. In addition, the key technologies used in these steam turbines are analyzed, such as steam flow exciting vibration prevention and overspeed protection as well as the structure of HP/LP casing. The advantages of the ultra-efficient turbine are also expounded as far as the security and economic performance are concerned. At last, suggestions are put forward on future improvements in the aspects of shafting supports and heat regenerative system, etc.
