摘要
本文针对一种燃用合成气的燃气轮机燃烧室,在以VXI总线为基础的测试平台上,进行了该型燃烧室的中压全尺寸动态特性实验研究,获得了燃烧室在点火及变负荷情况下的温度、压力、振动等重要参数的变化规律,对燃烧室动态压力信号进行了动态频谱及功率谱分析,初步探讨了影响合成气燃烧室稳定、高效、安全运行的相关因素及作用机理。
The present study focused on the development of a full-scale gas turbine combustor burning syngas from the coal-based multi-production. The dynamic features of a variety of parameters of the combustor, such as temperature and pressure during the procedures of startup and thermal load shifting , were measured and analyzed. The frequency and power spectrum of pressure fluctuation were analyzed by applying FFT methods. The results show that the pressure fluctuation has distinct patterns during startup and load-transition procedures. The relationship between these dynamic fea- tures and the stability, safety and efficiency of gas turbine combustors burning syn-gas are preliminarily discussed.
