In order to approach as near as possible the actual combustion process, a mode! With geometric similarities for moved-out burner is described which is applicable to non-isothermal jet.
为了使试验结果尽可能接近真实燃烧过程，本文提出一种适用于非等温射流的后移燃烧器几何相似模型。

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.
