摘要
为了计算一维分区段模型最大放热区段中温度的分布 ,以辐射换热为理论基础 ,将最大放热区段按照燃烧器的层次再分为 4个区段 ,建立了新的一维分区段计算模型 ,得到了更为详尽的沿炉膛高度方向上的温度分布。并且对某电厂的B&WB -1 0 2 5 /1 6.8-M型锅炉进行了计算 ,将新的一维分区段模型与原分区段模型和实验数据相比较 ,验证了本模型的正确性。
To calculate the distribution of temperature in one-dimensional fragment model. a new model was developed based on the theory of radiative heat transfer. The maximal radiative fragment was divided into four parts according to the combustor's layer. So more detailed temperature along the gas path of the furnace was achieved. Furthermore, a calculation to a power plant's boiler whose type was B&WB-1025/16.8-M was carried out. The results proved the new model's correctness.
