中文摘要	The effect of the secondary air swirl number on the number of particle impacts which affects slagging was studied to reduce slagging in utility boilers. The flow field was measured using PDA to validate the numerical simulations. The simulations agree well with the experimental data near the burner outlet. The flow field near a single burner outlet was then analyzed for various inner secondary air swirling numbers with the stochastic separated flow model as a postprocessor to calculate the particle impacts. The computation results indicate that total number of particle impacts is relatively small and that the number of impacts is inversely proportional to the swirl number.
