摘要

通过调查和收集电厂温排水的原体观测资料

采用实测资料分析和模型试验对比的方法

研究了地处甬江河口的镇海电厂温排水对取水温升的影响。研究表明:(1)在现有条件下镇海电厂取水水温已存在超出设计最高温度(33.5℃)的情况

过高的取水温升在部分时段已经影响机组运行效率;(2)依据原体观测资料测点布置的不同

分别采用固定参考点全过程分析取水温升随潮变化的方法和针对特征时刻的变参考点分析方法是可行的

可为布置在类似的感潮河段电厂取水口与排水口工程设计所借鉴。

Abstract

Through investigating and collecting the data of original field observation about warm water discharged from thermal power plants

and adopting methods of observed data analysis and comparison with the model test

the influence of warm water discharged from Zhenhai Power Plant located at the estuary of Yongjiang Rever upon the temperature rise of intake water has been studied.Study shows that:(1)the temperature of intake water for Zhenhai Power Plant has exceeded the maximum designed temperature of 33.5 ℃ in some time under present condition

the exorbitant temperature rise has been affecting the operation efficiency of units;(2)based on the difference of measuring points arrangement in data of original field observation

it is feasible to use method of analysing the temperature rise variation along with the tide in whole process of fixed reference points

and the method of analysing the varying reference points directing against a characteristic moment respectively

providing reference for engineering design of water-intaking hole and water-draining hole for other power plants situated on the estuaries.
