摘　　要：针对７５ｔ／ｈ水冷方型分离器循环流化床锅炉，利用自行设计的测试方法进行了炉内燃烧室不同位置的局部固体悬浮浓度的测量，确定了燃烧室近壁区沿高度方向及截面方向物料浓度分布，分析了测量结果，并根据测量结果，发展了炉内局部物料浓度的计算模型。这个模型对于该炉的容量放大有指导意义。Measurement of solid suspension density distribution in the furnace of a 75t/h circulating fluidized bed boiler (CFB) with the water cooled square separator was conducted with the probe developed by Tsinghua University. Local solid suspension densities along the height and the depth of the furnace were measured respectively. The measurement results are analyzed and the density distribution along the height and cross section are determined. According to the measurement data, a calculation model to estimate the local solid concentration is developed. This model will be used for scaling up design of the circulating fluidized bed boiler.
