The direction of grid lines in the burner block is consistent with the direction of pulverized coal jet, which can reduce false diffusion in the simulation.
在燃烧器区域处使网格线与煤粉射流方向基本一致，以有效地减小数值模拟中的伪扩散问题。

For premixed burner, burning temperature is highest, combustion focuses in the interior of spout mainly, and influence of swirling jet flow on mainstream is great.
完全预混式燃烧器燃烧温度最高，燃烧主要集中在喷口内部，主流受旋转射流影响大。
