摘　　要：对两种煤粉浓缩器丘体和百叶窗的浓缩能力进行了试验研究。结果表明，缩短一次风管道内导流板的长度是可行的。为了在合适的浓淡风比下达到稳定燃烧所需的浓淡比，给出了对应于丘体和百叶窗的导流板高度和浓缩器与导流板距离的变化范围。The concentrating ability of two types (i.e., brent and shutter) of pulverized coal concentrators was investigated and tested. The test results show that it is feasible to shorten the length of guide plate in a primary air pipe duct. To achieve a bias concentration ratio satisfying the requirements of stable combustion under a proper bias air ratio, the authors have specified the variation range of the following: 1. the guide plate height for the brent and shutter; 2. the distance between the concentrator and the guide plate.
