SGT5-4000F燃气轮机改进升级措施分析
摘要：目的 为了给我国自主重型燃机研发及后续改进升级提供技术参考和设计依据，分析了SGT5-4000F燃气轮机改进升级措施。 方法 通过对SGT5-4000F燃机相关文献和资料的收集整理、性能分析，总结出了该燃机自1996年引入市场以来，西门子为提高该燃机性能采取的一系列改进升级措施。 结果 通过提升压气机进气量、降低冷却空气量、采用液压间隙优化 (hydraulic clearance optimization，HCO)等技术提升燃机功率和热效率；通过采用预混值班级、优化燃烧器主旋流器叶型等措施提高燃烧室热声稳定性、降低NO x 排放；通过采用经过验证的新材料、新铸造技术等提高部件的耐用性、使用寿命和燃机运行灵活性。 结论 上述改进升级措施可作为我国自主重型燃机及其衍生型号未来进行改进升级的技术参考和设计依据。
Abstract:Objectives In order to provide technical reference and design basis for the research and subsequent upgrade of China’s independent heavy-duty gas turbine, a series of upgrade measures of SGT5-4000F gas turbine were analyzed. Methods Through the collection, organization and performance analysis of relevant literature and data on the SGT5-4000F gas turbine, a series of upgrade measures taken by Siemens to improve the performance of the gas turbine have been summarized since it was introduced to the market in 1996. Results Through the analysis, it can be concluded that Siemens’ upgrade measures include: increasing compressor mass flow, reducing the cooling air and adopting HCO to improve the power and thermal efficiency. The use of premixed pilot and optimization of the main swirler helps to improve the thermo-acoustic stability and reduce NO x emission. The validated new materials and new casting technologies can be used to improve the durability, life and operational flexibility. Conclusions The above technical upgrade measures can be used as technical reference and design basis for future improvement and upgrade of China’s independent heavy-duty gas turbine and its derivative models.
