Numerical Simulation on the Performance of Heat Transfer in the In-direct Cooling Tower with Desulfurizer Inside

摘要

According to a 2x600MW power plant, we used CFD program Fluent to conduct 3-d numerical simulation on the performance of heat transfer in the in-direct cooling tower with desulfurizer inside. The operating condition was selected as THA, and the velocity of the air outside was set as 0, 2, 4, 6 and 8m/s in turn. And then we analyzed the effect of the air velocity on the performance of heat transfer of cooling tower and the diffusion of flue gas discharged from the desulfurizer, respectively. As a result, the natural wind, with its velocity increasing, should have much more influence on the performance of heat transfer and the diffusion of flue gas. It was believed that our results should be of great significance to understand the operating pattern and increase the efficiency of heat transfer of this kind cooling tower.
