大型循环流化床锅炉高压流化风系统设计优化

Optimum Design for High Pressure Fluidized Air Systemof Circulating Fluidized Bed Boilers

为改善多台并联高压流化风机的运行条件,通过数值模拟和工程应用,对传统式和平行式高压流化风管的流场情况进行分析研究,得出后者可以改善风机运行工况的结论。该成果可以推广应用到其它类似的锅炉岛烟风煤系统。

To improve the parallel operating condition of multiple HP fans, the flow field of conventional type duct and parallet type duct will be analyzed respectively in this article, which comes to a conclusion that the latter is better for operation. This result could be used for the other similar system of boiler island.
