摘　　要：对三相循环流化床蒸发器流动沸腾传热机理进行了分析。建立了适用于烧碱法麦草浆黑液系统的三相循环流化床传热模型。验证实验表明模型计算值和实验数据吻合较好,最大偏差在30%以内。Flow boiling heat transfer mechanism in a three-phase circulating fluidized bed evaporator is analyzed, and then the heat transfer model used for wheat straw black liquor is proposed correspondingly. The experiment shows that the calculator values from the model agrees well with the experiment data and the maximum deviation is within 30%.
