摘要:
采用Fluent6.3软件对600 MW超临界火电机组自然通风间接空冷塔流动和换热性能进行了数值模拟,对不同的环境风速下空冷塔内流场特性和换热规律进行了研究.研究结果表明,空冷塔在风速为零的情况下流场较为稳定,散热量和通风量最大,随着风速的增大,空冷塔内流场发生了较大的变化,散热量和通风量都呈现下降趋势,对间接空冷机组的运行产生不利影响.研究结果为大型电站锅炉间接空冷塔的运行改造提供了理论依据.
Abstract:
The llow field charaeteristies and heat transler of the natural ventilation indireet air-cooling tower ir600MW supereritieal thermal power unit were numerieally simulated by Fluent6.3 at diflerent environmenwind speeds. The results indieate that when the wind velocity is 0, the flow field is relatively stable. The healdissipating capaeity and the ventilation quantity are the largest in the air-cooling tower under this condition.With the inerease of wind speed , large changes of the flow field inside the tower have taken place ,at the samtime ,heat dissipation and ventilation quantity showe a trend of deeline. lt can eause an adverse impaet on theoperation of the indireet air-cooling units. The results provide a theoretieal basis for the operation of indireelair-cooling tower in the large power plant unit.
