摘要
对锅炉后烟道进行技术改造后,因烟道阻力增加,原有的引风机和增压风机压头不足,需同时进行风机的升级改造。在系统中采用了引增合一的联合风机,改进了逻辑控制电路,提高了风机的自身保护能力,取得了较好的效果。
After the technical reconstruction of boiler flue, the original pressure heads of induced draft fans and booster fans are not sufficient, which are needed to be updated and reconstructed. We use united fan and improve logical control circuits. After that self protection of the fans are improved.
