摘　　要：采用图像处理方法 ,可视化研究非均匀布风内循环流化床中的气泡特性。用CCD摄像机将拍摄的数字图像进行处理 ,从而得到清晰的气泡图像。研究不同流化速度及床层高度处的气泡形状和尺寸 ,同时对内循环流化床中的气泡破裂与合并现象进行分析。The characteristics of bubbles in internally circulating waste incinerators are visualized researched by image processing method in this paper.Digital photographs snapshot by CCD camera are dealt with,then distinct photographs of bubbles can be obtained.The shape and scale of bubbles at different fluidized velocities and bed's height are researched in the paper,at the same time,the breakage and merger of bubbles in internally circulating waste incinerators are analyzed.
