经测试和分析认为包头第一热电厂 ８ 号炉送风机风道振动的原因是由气流脉动所致，经采取加装均流减振装置和导向板等措施进行改造后，使振动明显减小。 After the test and analysis, it is thought that the reason of the vibration of the blower duct of the No.8 furnace in Baotou No.1 Thermal Power Plant is caused by the pulsation of the air flow. After the measures such as installing the current-sharing vibration damping device and the guide plate are taken, the vibration is obviously reduced.
