300Mw机组容量脱硫喷淋塔内部流场模拟研究

摘要

By using Fluent software,we have conduct numerical simulation for 300 Mw unit capacity of the desulfurization spray tower for the internal flow field,and use Gambit software to mesh the model into unstructured tetrahedron grid.We research that different gas entry form,different entry Angle have different effects.The result show that 120° and 180° double entry flue,when the entrance angle was 15° and inclined down,it has a good flow field distribution.%采用Fluent软件对300 Mw机组容量的脱硫喷淋塔的内部流场进行了数值模拟,使用Gambit软件对该模型采用非结构化四面体网格进行网格划分。研究了烟气的不同的入口形式,不同的入口角度对流场的影响。结果表明：120°和180°双入口烟道,入口角度为15°斜向下时,具有较好的流场分布。
