摘　　要：为了提高中亚管道压气站燃气轮机出力,降低能源消耗,选取中亚天然气管道A站4#燃气轮机和B站3#燃气轮机为代表对中亚管道全线不同机型压缩机组进行节能测试,测定不同工况下的压缩机效率,并对比分析了GE普通机组与DLE机组的能效差异。结果表明:GE普通机型运行效率高,但燃料的烟气排放量高;DLE机型由于采用了更复杂、更环保的燃烧工艺,燃料的烟气排放量低,但其运行效率也较低,每小时耗气量高,节能减排方面无明显优势。该结果可为中亚管道节能降耗工作的开展提供数据支撑,也可为国内后续选购压缩机机型提供技术支持。In order to increase the efficiency of gas turbines in the compressor stations of Trans-Asia Gas Pipeline and reduce the energy consumption, energy saving tests are conducted on the compressor units of different types along the Trans-Asia Gas Pipeline by taking 4# gas turbine in Station A and 3# gas turbine in Station B as the representatives. The efficiency of the compressors is measured in different operating conditions, and the difference of energy efficiency between GE conventional unit and DLE unit is compared. It is shown that the GE conventional unit is higher in operating efficiency, with higher fuel flue gas drainage, and the DLE unit is lower in flue gas drainage due to its more complicated and more environment-friendly combustion process, with lower operating efficiency and higher gas consumption per hour. The later has no obvious advantage in energy saving and emission reduction. These findings provide not only data support for the energy saving and consumption reduction in Trans-Asia Gas Pipeline, but also technical support for the selection and purchase of gas compressors in the future in China.
