摘要
以某大型电厂为例,应用计算流体力学方法模拟大气逆温对冷却系统运行带来的不利影响。结果表明:大气逆温会降低冷却塔抽力,进而影响冷却效果;由于该电厂的间接空冷系统冷端规模大,其对大气逆温等不利自然因素的缓冲能力较强,一般强度大气逆温对冷却塔工作的影响尚在可以接受的范围内。
The numerical model was applied to simulate the impact of temperature inversion to cooling tower. The result shows that： atmospheric temperature inversion will reduce the power of cooling tower, and then affects the cooling effect. As the scale of the power plant indirect air-cooled system is Strong ability to buffer, The general atmospheric temperature inversion intensity to the cooling tower work is still acceptable.
