输入燃气轮机燃烧的天然气燃料的压力稳定对燃气轮机的稳定运行非常重要,天然气的压力波动必须控制在燃气轮机许可的范围之内,因此对燃气轮机的天然气供气系统的压力稳定性要求十分苛刻,国内燃机电站大部分用的是减压系统,技术非常成熟,但是对增压站系统,尚在探索和实践中,会出现一些意想不到的问题,如何分析和解决这些问题对未来的增压系统燃机电站有着切实的指导意义。SGT5-2000E燃机天然气供气系统中配置离心式增压机在调试过程中遇到了压力波动导致燃机不能稳定运行甚至跳机的问题,如何解决呢?
The pressure stability of natural gas fuel fed into the gas turbine is very important for the stable operation of the gas turbine. The pressure fluctuation of natural gas must be controlled within the allowable range of the gas turbine. Therefore, the pressure stability of the natural gas supply system of the gas turbine is very demanding. Most of the decompression system is used, the technology is very mature, but the pressurized station system is still under exploration and practice, there will be some unexpected problems, how to analyze and solve these problems for the future pressurized system gas turbine power station Has a practical guiding significance. SGT5-2000E gas turbine gas supply system configuration centrifugal turbocharger in the debugging process encountered pressure fluctuations led to the stable operation of the turbine or even the problem of the trip, how to solve it?
