Abstract
To further develop the application of the biomass fuel in gas turbine combustor, the wave convection model was conducted based on the experimental results to quantitatively analyze the influence of n-butanol/kerosene mixing ratios on the pressure oscillation frequencies in a non-premixed combustor. The experimental results show that the pressure oscillation frequencies decrease with the increasing volume proportion of butanol under the experimental condition of com bustor inlet pressure 1.98 MPa, inlet temperature of 600 K and fuel/air ratio of 0.03. However, the amplitudes have no significant changes with the increase of volume proportion of butanol. The results of wave convection model are in good agreement with the experiment data. The calculation results show that the variation of convective time caused by the variation of heat value of different fuel components is the main cause of the variation of pressure oscillation frequencies. It provides reference for the control of pressure oscillation in a non-premixed combustor.
