华能玉环电厂一次风机和送风机设计裕量的选择

Primary Fan and Blower Design Margin Selection of Yuhuan Power Plant

华能玉环电厂是我国首台自主设计的1 000 MW超超临界机组工程,其一次风机和送风机风量和压头设计裕量没有现成的设计规范可遵循。通过对国内外1000MW等级机组的风机配置方式,风量、风压裕量的取值以及国外设备制造厂的有关设计导则进行分析,对玉环电厂一次风机和送风机设计裕量进行了选择和分析,并对1000MW机组一次风机和送风机的设计提出了相应的建议。

Huaneng Yuhuan Power Plant uses China＇ s first independently developed 1000 MW USC units. There are no existing design criteria for primary fan and blower volume and pressure head design margins. By analyzing fan configurations, volume, pressure margin of domestic and foreign 1 000 MW class units, as well as foreign manufacturers＇ design guidelines, primary fan and blower design margins of Yuhuan Power Plant are selected and analyzed. Suggestions are also brought forward on 1 000 MW unit primary fan and blower design.
