Flow Field and Particle Distribution in Horizontal Thick and Thin Firing Burners

Abstract:

A numerical simulation study on the horizontal thick and thin firing burner with distorted clapboards was conducted based on the realizable k–ε turbulence and Lagrange random particle orbital models. The flow field and pulverized coal concentration distribution were also determined. Moreover, this study achieved the following results. The velocity distributions in the burners with clapboards at 40°, 90°, and 140° distortion angles were close to the experimental values. The separation degree of pulverized coal concentrations in this kind of burner was higher, and the airflow rotated forward in a clockwise direction. Lastly, the thick and thin side air distributions were right- and left-skewed at the exit, respectively.
