摘　　要：详细介绍了锅炉吹灰减压站的系统构成,蒸汽管路导通状态,并给出了一种新的吹灰减压站的逻辑控制方式,该控制方式完全避免了先导式电磁阀由于先导压力不足无法实现气路顺利切换的固有缺陷是一种极佳的控制方式。This structure of the soot blowing pressure-reducing station in the boiler system, the open condition of the steam tubes and produced a new logical control method to the soot blowing pressure-reducing station is introduced in detail. The solenoid valve cannot achieve the switch among the steam routes great in case of the lack of pressure, this control method avoids the immanent limitation as mentioned above.
