国内首台亚临界中间再热125 MW等级背压机组设计研究

摘要

亚临界中间再热背压机组是提高背压供热机组热经济性的重要技术方向, 相对于目前的背压机组, 其在经济性上具有较大优势.本文结合国内首台亚临界中间再热背压机组的设计和系统介绍, 对工程的方案设计进行简要的分析研究.设计成果将在实际工程中得到应用, 对背压机组的技术发展起到一定借鉴意义.%The subcritical reheat backpressure unit is an important technical direction to improve the thermal economy of back pressure heating units.Compared with the current back pressure unit, it has a greater economic advantage.In this paper, combined with the design and system introduction of the first subcritical intermediate reheat back pressure unit in China, the design of the project is briefly analyzed.The design results will be applied in practical engineering, which will be of important reference for the technical development of the back pressure unit.
