摘要：

The natural wind plays disadvantageous roles in the operation of air-cooled steam condensers in power plant. It is of use to take various measures against the adverse effect of wind for the performance improvement of air-cooled condensers. Based on representative 2x600 MW direct air-cooled power plant, three ways that can arrange and optimize the flow field of cooling air thus enhance the heat transfer of air-cooled condensers were proposed. The physical and mathematical models of air-cooled condensers with various flow leading measures were presented and the flow and temperature fields of cooling air were obtained by CFD simulation. The back pressures of turbine were calculated for different measures on the basis of the heat transfer model of air-cooled condensers. The results show that the performance of air-cooled condensers is improved thus the back pressure of turbine is lowered to some extent by taking measures against the adverse impact of natural wind.
