摘　　要：针对某350MW超临界双转子低真空供热汽轮机的热力设计问题,对双转子设计的目的、高背压通流设计以及低真空供热特性等相关设计问题进行了全面的论述及分析。结果表明:采用双转子方实现低真空供热方式后,机组的供热能力大幅提高,供热经济性大幅变好,供热需要的最小电功率降低。As for the problem of a350MW super-critical unit with two rotors for low-vacuum heat supply,detail dicusses and analysis about some design problems such as heating charactoristic,flow path design and so on are deducted.The result shows that after using low vacuum heating technology,the unit heat supply capacity has been greatly improved,the operation economy has been improved too,and the minmum electric power for heat supply has been reduced.
