  7. 7. 主机Ff配置方案介绍 – Ff Application in Unit DCS 本工程在锅炉有众多二次风分风门采用Ff现场总线技术 – Ff Application in Boiler Secondary Air Damper Control − 设计初衷:由于锅炉二次风分风门众多(74个),原先设计为1个 DCS指令控制一组风门,风门没有位置反馈不利于燃烧控制与管理, 且需要大量的控制电缆及接线。为了更好的控制管理这些二次风分 风门及节省安装调试成本顾选用了Ff总线技术。根据二次风分风门 比较集中的特性,每台机组分了12段Ff总线 − 74 sets Boiler Secondary Air Damper of each boiler, One DCS command Signal for each group damper, diFficult combustion control due to no feedback for damper position. Too much control cable and wiring. With Ff bus application: Less cable & installation, and better control & management, 12 segments for each boiler。
