某热电厂循环水系统静特性分析
Static Characteristic Analysis on Cooling System of a Thermal Power Plant
摘要:
利用一维数学模型对某热电厂循环冷却水系统进行了计算分析。考虑循环水管路及各主要设备阀门的阻力特性,计算得到了整个冷却水管网阻力特性曲线。并结合泵特性曲线,分析了循环水泵组与管网匹配后的系统特性及流量特性。为循环水泵系统实际运行提供理论基础。
Abstract:
The cooling water system of a certain thermal power plant has been simulated using one-dimensional method. The drag characteristic of circulating water pipe and main value has been considered, so the whole pipe net drag characteristic curve was calculated, with combinations of axial pump operating curve, the static operating and flow characteristics of the cooling water system have been analysed. This paper could provide some references for the cooling water system real operation.
