| 摘 要： | 潮汐河口地区,温排水的扩散比较复杂,温排水对电厂本身的取水温度会产生影响。取水温度难以满足机组运行要求时,普遍采用的是取排水工程的改造,为简化,可以建导流堤对温水进行人工导流。通过建立二维温排水数学模型对导堤改造方案进行比选,研究各方案的温水团导流作用对取水温升的改善效果。结果表明,各导堤方案均有较好的改善效果,堤顶高程为中潮位的方案较优。

| Abstract: | Thermal drainage is quite complicated in tidal estuary,and it will produce an effect on the intake water temperature of power plant.When the temperature of intake water can not meet the needs of operating the generator sets,the most commonly scheme is reconstructing water intake and drainage project.To simplify we can construct drainage jetty for artificial diversion.Comparing various schemes through modeling the 2 dimensional thermal drainage mathematical model,we analyzed on the effect of thermal drainage in bringing down the temperature of intake water.The results shows each scheme can gain preferable effect,but the scheme with jetty crest altitude equaling to mean tidal level is the best. |
