一种工业燃煤锅炉风机节能方法研究

摘要

本文介绍一种采用西门子S7-200PLC控制变频器来实现工业燃煤锅炉鼓风机的无级变频调速，实践证明，与传统的控制方式相比，该调速系统可靠性更高，节电效果明显。%Siemens S7-200 PLC was applied to the inverter controller in order to realize stepless frequency speed regulation on industrial coal-boiler blower. Practice approved, this system possessed higher reliability and energy- saving advantage as compared with traditional controlling method.
