摘　　要：用从美国引进的先进的速度测试仪器─—热线风速仪，对某炼铁厂3号高炉换热器前流道流场进行了冷态模型试验。试验结果表明：在高炉煤气换热器前流道中形成了较大的涡流区，且这涡流区是造成高炉换热器管束破损的主要原因。A cold model test was carried out on the front-runer flow field in a BF gas heat exchanger.The velocity field was measured with the hot wire anemometer made in USA. The test results showed that the velocity field was not uniform in the front-runner of the exchanger. A high speed vortex was generated there, which caused the heat exchanger out of order.
