| 摘 要： | 介绍了冷却塔烟气排放原理及德国VDI 3784的S/P模式，结合实例研究了冷却塔烟气排放不同参数、不同大气条件下烟气抬升高度变化特征，并使用德国VDI 3945的Austal 2000模式对冷却塔和烟囱的排放浓度进行了对比。结果表明：烟气抬升高度主要取决于出口温度和环境温度之差；随着风速的增大，抬升高度明显变小；随着直径的增加，烟气抬升高度也增加；随着出口速度的增加，抬升高度增加的相对较多；随着出口温度的增加，烟气抬升高度在逐渐增加，稳定度决定增加的倍数；VDI 3945模拟结果表明：小时浓度差别相对较小，而年均浓度差别较大，日均值的差别介于小时和年均之间。

| Abstract: | The theory of flue gas emission and S/P model in Germany VDI3784(the environmental meteorology dispersion modeling for flue gas discharge through cooling tower)were introduced.The characteristics of the parameters and uplifted height of flue gas under different atmospheric conditions were analyzed by the example.Flue gas concentrations from cooling tower and chimney were compared by Austal 2000 model in Germany VDI 3784.The results indicate that uplifted height of flue gas could be determined by the differe... |
