摘　　要：合理的一次风速是保证电站锅炉安全经济运行的重要条件,锅炉一次风速的准确测量对锅炉的启动调试、燃烧调整等工作有着直接的影响,是关系到机组安全稳定经济运行的重要课题。本文通过对一次风管道内的流动状况的数值模拟,揭示了复杂管道条件下的一次风流动特性,为准确测量一次风速提供了依据。It is very important in the operation of utility boilers to control the primary air velocity in a suitable range. The measuring of primary air velocity is especially important in boiler commissioning and combustion optimizing. By numerical analog, the flow characteristic of the primary air in a complex pipe condition is revealed, which is the basis of the accurate measuring.
