宽调节比燃烧技术的研究

On Combustion Technology of WR Burner

本文从试验和数值模拟两个方面对宽调节比（ＷｉｄｅＲａｎｇｅ，简称ＷＲ）烯烧器的一次风弯管内气固两相流动，燃烧器钝体后两相流场，以及钝体后混合流场进行了研究，综合分析了燃烧器稳定燃烧机理，并提出了改进措施。研究结果为大型电站燃烧系统的设计及运行提供了重要依据。

In this paper,a Wide Range (WR) burner has been studied on gas-solid flow in primary air pipe,bluff-body burner and mixing two-phase flow field,experimentally and computationally. Furthermore,the name stability mechanism of burner has been analyzed comprehensively and improvements have been Put forward. The results will give evidences to design and operation of burner in power plant.
