长江下游沿江热电厂温排放试验研究

本文根据冷却水物理模型试验关键相似条件,对长江下游扬州DE电厂扩建工程物理模型进行了设计.通过对二、三期取排水口工程布置方案在各种水文条件下的温差水流试验,得到了表层温度分布场和垂向温度分布,论证了取排水口布置和型式,并对二期取水口的位置进行了优化设计,为DE电厂扩建工程的设计及环境评价提供了相应的科学依据.

Thermal Flow Outflowing Test for the Power Plant at the Downstream of Yangtze River

According to the key similarity criteria of physical model for cooling water , its design for Yangzhou DE power plant at the downstream of Yangtze River in extension stage was introduced in the paper. The temperature difference flow test under the different conditions of hydrology for intake and outlet works in the second and the third stage of construction were conducted , the temperature field of surface layer and vertical temperature distribution were measured , the positions and types of intake and outlet were demonstrated , and the optimal design was carried out for the position of intake in the second stage . The test results can be used as scientific basis for design and environment assessment of the extension project of DE power plant .
