摘　　要：火力发电厂烟气排放流量测量不准确是影响环保监测的重要因素。应用CFD软件对某电厂脱硫后烟道内气流分布进行数值模拟。对比了矩形烟道脱硫前后的几何模型,介绍了数值模拟结果与试验结果速度分布趋势并阐述了试验结果。Inaccurate measurement of flue gas flow rate in power plant is an important parameter to influence environmental monitoring.The paper is numerical simulation for flue gas distribution in the gas duct in the back of desulphurization with CFD computation software.It showed that the comparison between numerical simulation values and experimental results indicates that the trend of velocity distribution was quite coincident.The experimental results were introduced.
