Allocation and Optimization of the Cooling Tower About 1 000 MW NPP
-
Abstract
Based on the 1000MW nuclear power station cooling tower's allocation and optimization, the high-level water collecting cooling tower's annual operating costs is less than the conventional tower's, it's used by collection device, and can effectively reduce the pump geometry head, and also can save the annual operating costs. The larger of the filling area, it can get the more economic advantages of using high-level collection device. The numerical simulation according to the conclusions, the high-level water collecting cooling tower should be used by depth optimization about filling arrangement, reducing the thickness of the external filling, increasing the thickness of the internal filling, and ultimately finishing the overall thermal performance of the cooling tower.
