摘　　要：持续推广背压式汽轮机供热技术,是推进节能减排工作的重要方向之一,将大型火电汽轮机中增加再热、回热系统优化、分级调节供热等提高效率的措施应用到背压式汽轮机上,可进一步提高能效水平。与此同时,上述节能措施增加了系统的复杂程度,也给机组运行增加了难度。本文以某工程配套的超临界再热型双抽背压式汽轮机为例,对其运行策略进行分析,以供同类机组参考。It is one of the important directions to promote energy saving and emission reduction promoting the heating technology of back-pressure turbine continuously.Transferring the measures increasing efficiency,such as reheating,heat regenerative system optimization,graded regulation of heating,from large thermal turbine to back-pressure turbine can improve the energy efficiency furtherly.Furthermore,the energy saving measures above-mentioned increase the complexity of the system,but also increase the difficulty of unit operation.This paper takes the supercritical reheating double extracting back-pressure steam turbine for some project as an example to analyze its operation strategy for reference of similar units.
