| Abstract: | 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 features and the stability, safety and efficiency of gas turbine combustors burning syn-gas are preliminarily discussed. |
