冷却水是保证火电厂正常运行的必要条件,取水防沙条件的好坏对电厂的安全运行至关重要。大唐火电厂取水河段处于昭化水电站回水区,属于弯曲型河道,泥沙特性复杂,为保证取水安全、可靠,采用物理模型试验与数值模拟相结合的方法对取水工程河段的泥沙特性进行研究,并预测了取水河段多年后的泥沙淤积情况。结果表明,大唐火电厂取水河段短期内无推移质淤积,多年后泥沙淤积较少,取水口位置选取较为合理。
Cooling water is a necessary condition to ensure the normal operation of thermal power plants. The quality of water and sand control is crucial to the safe operation of power plants. The water intake section of Datang Thermal Power Plant is in the backwater area of Zhaohua Hydropower Station and belongs to a curved channel. The characteristics of sediment are complex. In order to ensure the safe and reliable water intake, the physical model test and numerical simulation are used to simulate the mud Sand characteristics of the study, and predict the water intake after years of sediment deposition. The results show that Datang thermal power plant water intake in the short term without mass deposition of siltation, sediment deposition less after many years, the location of the water intake more reasonable.
