为了缩短重型燃气轮机燃烧器修复和低氮燃烧技术开发周期，打破F级重型燃气轮机热部件制造技术壁垒，基于增材制造技术，开发出了一套完整的F级燃气轮机燃烧器加工工艺，成功实现了标准产品旋流器的试制。在此基础上，利用增材制造技术生产的燃烧器，完成了在役燃气轮机燃烧器的服务修复；在新型低氮燃烧技术开发中成功试制出多款自主开发的新型低氮燃烧器，并通过了全温、全压、全尺寸实验验证；批量生产了产品级新型低氮燃烧器，贯通了F级重型燃气轮机燃烧器从设计开发到工艺开发的全部流程。实践表明，运用增材制造技术可助力企业在燃气轮机服务、研发和生产等方面实现快速创新。

In order to shorten the development cycle of burner repair and low NOx emission combustion technology for heavyduty gas turbine,and to break the technical barrier of manufacturing hot parts,a complete set of processing technology of the Fclass burner was developed by using additive manufacturing technology.The standard hydrocyclone has been successfully trailproduced .On this basis,damaged burners on units has been replaced by using the burners made by additive manufacturing technology.In the development process of new low NOx emission combustion technology,a number of burners have been produced and verified by full temperature,full pressure and fullscale experiments.the new type of low NOx emission burner has been successfully produced in batch.From concept design to manufacturing,the development process of Fclass heavy duty gas turbine burners has been thoroughly opened up.These applications show that additive manufacturing technology has great potential to bring substantial values to enterprises in gas turbine service,R&D and manufacture.
