运用气固两相流动的相似理论，对电厂实际煤粉空气两相流动进行了模化，就竖直向上转水平弯曲圆管内气固两相流动作了试验分析和理论探讨，分别就不同弯曲半径、不同煤粉进口浓度和不同隔板长度下浓淡分离程度以及弯曲圆管后水平段内煤粉颗粒的恢复特性进行了试验研究，并从弯管浓淡分离效果角度对ＣＥ－ＷＲ燃烧器进行稳燃理论分析，得出了一些有意义的结果，可为电厂实际运行工况的组织与调整提供依据。 Based on the similarity theory of gas-solid two-phase flow, the two-phase flow of pulverized coal in the power plant was modeled. The gas-solid two-phase flow in the horizontal curved tube was turned up and down to make the experimental analysis and theoretical discussion. Radius, pulverized coal inlet concentration and different partition length, and the recovery characteristics of pulverized coal particles in the horizontal section after curved pipe were studied. The CE-WR burner Steady combustion theory analysis, come to some meaningful results, which can provide the basis for the organization and adjustment of the actual operating conditions of the power plant.
