| 摘 要： | 烟囱的有效烟气高度是计算地面浓度的一个重要因素,目前,有许多烟气抬升公式被用在大气质量模型中,本文介绍了一些烟气抬升公式,即Briggs,Holland.moses和Carson,GB,Lucas.Concawe,Csnady,TVA和静风公式等.其烟囱有小的、中的、大的和极大的各种,这些公式计算的结果在它们适用的范围内做了对比,根据计算的数据,得到了一个新的烟气抬升公式如F:△H=(0.92V,D+5.25Fb0.4Hs0.6)/u,该公式可广泛地应用于大气质量模型。并给出满意的结果

| Abstract: | The effective plume height of chimney is an important element in calculating ground level concentration. Now. many plume rise formulas are used in the air quality model. This paper shows the calculation by several plume rise formulas, i. e. Briggs, Holland, Moses and Carson, GB, Lucas, Concawe, Csnady, TVA and calm, with small, middle, large and very large chimneys. A comparison among the calculating results from these formulas has been made with their suitable application spheres given. Based on the data from the calculation a new plume rise formula has been obtained as follows : △H=(0. 92 VsD+5.25Fb0.4Hs0.6)/U It can be used widely to air quality model, and gives a satisfatory result |
