焙烧炉燃烧站控制系统应用及维护

燃烧站在氧化铝焙烧炉生产中起着举足轻重的作用，没有燃烧站的正常运行，焙烧炉就无法投入生产，而燃烧站的启动和停止都是由S5—95U小型PLC自动控制系统来完成，自动控制系统的运行情况直接关系到燃烧站的工作，因此，对系统结构、工作过程及程序的理解及对输A／,输出硬件的维护就显得极为重要。为此，本文针对这一自动控制系统的重要性，介绍了SIEMENS S5—9UPLC控制系统的组成、控制过程原理、控制功能及硬件组成，介绍了该PLC自动控制技术在焙烧炉燃烧站自动控制系统中的应用情况以及系统维护的经验。

The aplication and maitenance of control system of burners of calciner

The burners of calciner play a dey role in the production,and the calciner cannot be put into production without the normal running of burners.The start-up and stoppage of burners are controlled by SIEMENS S5-95U PLC control system.The paper is to introduce the constitution,control principle,function and hardware of this control system.The application of PLC control technology for calciner as Well as the maintenance experience are also introduced.
