来流流速对水域环境及标准发电煤耗的影响

Effects of Different Stream Flow Rate on the Aquatic Environment and the Standard Coal Consumption

以Fluent软件为平台,以差位式取排水布置方式为例,在不同来流流速下对电厂的取排水进行数值模拟。根据数值模拟结果,分析了不同工况下取排水对水域环境的影响,并以上述模拟结果为基础,通过等效焓降法,分析其对凝汽器标准发电煤耗的影响,为机组的运行提供参考。

Fluent software as a platform, taking differential bit-taken drainage arrangement as an example, power plant intake and drainage is numerically simulated under different stream flow rate. According to the results of numerical simulation, the analysis on the impact of thermal discharge on water environment in different working conditions is conducted. Based on the simulation results , by the equivalent enthalpy drop method , the impact on the the condenser standard coal consumption is analyzed , which can provide reference for the operation of the unit.
