摘要
水平浓缩煤粉燃烧器（ＨＢＣ）可以同时实现煤粉的高效燃烧、防止结渣、稳定燃烧和低ＮＯｘ排放。一种基于惯性力浓缩的新型煤粉浓缩器──百叶窗式煤粉浓缩器是实现水平浓缩煤粉燃烧的关键。成功地采用这种百叶窗式浓缩器需要研究四个问题：阻力特性、气流和压力分配特性、浓缩特性和耐磨特性。本文着重研究结构参数对浓缩器阻力损失的影响。实验结果表明，随着百叶窗浓缩栅个数和间距的增加及浓缩栅倾角的增加，百叶窗浓缩器的阻力损失减小。
With the use of a horizontal concentration pulverized coal burner it is possible to effect a simultaneous realization of highly efficient burning of pulverized coal, prevention of slagging, stable combustion and low NOx emissions. A novel type of inertia-based concentrator of pulverized coal, the louvered concentrator plays a key role in attaining the combustion of horizontal concentrated pulverized coal. Its successful application necessitates the study of the following four issues: resistance characteristics, the distribution of air flow and pressure, concentration characteristics and wear-resisting properties. This peper focuses on the investigation of the effect of structural parameters on concentrator resistance ]on. The test results show that with the increase on the number of louvered concentration grid units and their clearance and the increase in concentration grid inclination the resistance loss of the louvered concentrator tends to decrease.
