| 摘 要： | 奥里油燃烧后的排放物温度以及SO2浓度比较大，为了对电厂周围环境质量进行分析，采用CFD软件进行模拟。模拟了奥里油电厂高架连续点源的烟羽传输与扩散, 根据湛江市有代表性的年平均气象数据，采用Fluent软件分析了不同大气风速和湍流度下奥里油电厂烟羽传输与扩散的特殊规律, 给出了描述大气污染的两个重要参数最大落地浓度及离源距离和烟羽中心线抬升高度及离源距离的下风向沿程变化情况。数值计算结果与烟气扩散理论和经验数据是相符合的, 所以该模型可以较好的模拟奥里油电厂烟羽的传输与扩散的特殊性，从而为该电厂的环境影响评价提供依据。

| Abstract: | As Orimulsion combustion characteristics, dispersion law of power plant emissions has its particularity. Take plume transmission and dispersion of high chimney emission point-source in orimulsion-fired power plant for an example, use phoenics3.6.1 to discuss the influence to plume transmission and dispersion in different conditions such as wind velocity and turbulence intensity. Calculate four factors such as concentration on the ground along plume axis and its distance, the plume rise height along plume axis and its distance. Comparing the numerical results with the data based on the similar experiments, the numerical simulation of plume transmission and dispersion in orimulsion-fired power plant is feasible. |
