摘要: Abstract This study investigates how changes in turbulator angles affect on combustion characteristics of a low calorific value syngas generated burner integrated with combustor. Turbulator were changed from 15° to 45° at intervals 15°. Simulations have been performed by using CFD code. PDF/Mixture Fraction and k-e standard turbulence models used during the modellings. Temperature predictions flame are compared existing temperature measurements. It is determined that these satisfactorily good agreement Then, modellings made under 30° conditions each other. revealed change affects highly temperature, emission velocity gradients throughout combustor whereas pressure drop slightly influenced near inlet zone. also concluded high zone moves upstream due effect tangential as angle increased. Predicted axial values decrease center because angle.
