| Abstract: | The air formation of swirling burners is significant to the stable burning and safe operation of the boilers. Numerical simulation study is carried out by setting up physical and mathematical model against central feeding swirling burners based on CFD numerical software platform. The distribution of velocity field and vector under different operating conditions is obtained by adjusting primary and secondary air volume, thus the rules affecting different permitted parameter against flow field is obtained. |
