6FA燃气轮机试车台排气系统研究

Research on Exhaust System of 6FA Gas Turbine Test-bed

针对国内某6FA燃气轮机试车台的排气系统进行性能研究,阐述了燃气轮机试车台排气系统的作用、组成、性能和潜在问题等。通过声学和热力学分析,重点讨论了6FA燃气轮机试车台排气系统的噪声、保温性能,并对未来运行过程中可能出现的问题进行探讨。试车台用燃气轮机排气系统与电站用燃气轮机排气系统有很大区别,给同类型燃气轮机试车台的排气系统搭建提供参考。

To study the performance of the exhaust system of a 6FA gas turbine test-bed in China,and describe the function,composition,performance and potential problems of the exhaust system.The noise,thermal insulation performance and possible problems in the future operation of the exhaust system of 6FA gas turbine test-bed were discussed through acoustic and thermodynamic analysis.There is a great difference between the gas turbine exhaust system of the test-bed and that of the power station,which provides a reference for the exhaust system construction of the same type test-bed.
