摘要

介绍了基于涡旋引擎原理的烟塔合一系统

结合600 MW机组的烟囱及冷却塔以50∶1的比例建立其数值模拟模型

利用RNGk-ε湍流方程对该模型进行分析求解

得出其温度场、压力场、速度场、密度场与理论分析基本吻合

而且涡旋加强室及稳定室水平线温度的模拟值与试验值也基本吻合。测量得烟塔合一系统的冷却水入口温度为29℃、出口温度为25℃

冷却水出口温度明显低于入口温度

说明该烟塔合一系统具有很好的冷却效果。

Abstract

To take full advantage of heat in flue gas

improve the unit efficiency

and reduce the pollutant emission

a new vortex engine theory based natural draft cooling tower with flue gas injection system was presented.By computational fluid dynamics software ANSYS-CFX

a numerical simulation model was established at ratio of 50∶1according to the actual chimney and cooling tower of a 600MW unit.The RNGk-εturbulence equation was applied to analyze this model

and the obtained temperature field

pressure field

velocity field and density field were basically consistent with the theoretical analysis.The simulated value of the temperature at horizontal plane of the strengthened vortex chamber and the stable vortex chamber agreed well with the experimental values.The measured cooling water temperature at inlet of the unification system was 29 ℃ and that at outlet was 25 ℃.The outlet cooling water temperature decreased significantly

indicating this unification system had good cooling effect.
