对中等功率ГТЭ-65发电用燃气轮机装置研制过程和设计理念,包括热力系统参数的选择、3大部套(压气机、燃烧室和涡轮)的设计及其特点、主要部件的模型和试验台试验、应用的可能性和进一步升级改进的途径做了综述.利用已有的研制成果,使用按比例绘制的方式,对压气机采用了全模拟设计.按照DLN或DLE原理,满足为实现燃料低排放燃烧的一系列条件,设计了低排放环形燃烧室.通过方案比较,采用了4级涡轮设计.除第四级动叶外,涡轮所有叶片都是冷却的.ГТЭ-65是符合当代“F”级技术水准的一型中等功率燃气轮机,既可用于简单循环燃气轮机电站,也可用于基于燃气轮机的蒸燃联合循环电站;既可用于基本负荷运行,也可用于半峰值和峰值负荷运行.“,”An overview was given of the development process and design philosophy of a newly-developed ГТЭ-65 type power-generation gas turbine, including the choice of the parameters for the thermodynamic system, design and features of the three major components-compressor, combustor and turbine, models and test rig tests for the main components, possibility of their applications as well as further upgrading approaches. By making use of the currently available achievements and employing a plotting mode at a proportional range, a full-scale simulation design was adopted for the compressor. According to DLN (dry low NO_x) or DLE (dry low emissions) theory and by meeting various conditions for achieving low-emission combustion of the fuel, designed was a low-emission annular combustor. Through a comparison of various versions, the four-stage turbine design was finalized. Apart from the rotating blades in stage No.4, all the turbine blades were cooled. The ГТЭ-65 type gas turbine is regarded as a medium power one meeting modern“F”class technical level and can be used for both simple cycle gas turbine power plants and gas-turbine-based steam-gas combined ones, applicable for not only basic load operation but also semi-peak and peak load one.
