An Ignition Control System of Regenerative Heating Furnace

摘要:

针对硅钢退火工序中传统加热工艺的能源利用率低、污染程度高、组网复杂、监测灵活性差等问题,在充分研究蓄热式加热炉及配套的点火控制器工作原理的基础上,设计了一套可以远程监测和管理的点火控制系统;利用PT100温度传感器采集烟道温度数据,单片机C8051F060作为数据处理核心,将多台点火控制器与上位机进行组网通信,通过数码管和按键进行人机交互,配合温度检测和煤气阀门控制电路,实现控制烧嘴合理运行;结果表明,各个点火控制器能够实时与上位机通讯,吹扫、交替点火、正常燃烧等步骤能够正常进行,减少了报警状态下的人工干预,降低了劳动强度;本系统成本较低,可拓展性强,易于安装和维护,已经投入实际生产中,并取得良好的效果。

Abstract:

For traditional heating process in silicon steel annealing process, such as low of energy efficiency, high of pollution degree, complex of networking, poor of monitoring flexibility.In the full study of regenerative heating furnace and the ignition controller on the basis of the principle of form a complete set, designing a set of remote monitoring and management of fire control system. Using PT100 temperature sensor to gather flue temperature data and microcomputer C8051F060 as the core of data processing, making more than one ignition controller network communication with PC,and interacting human through digital tube and buttons.Cooperate with temperature detection and gas valve control circuit,making control burner operate reasonable. Results show that various ignition controller can communicate with PC real-time.At the same time ,proper steps such as purging ,turning the ignition and normal combustion can run. Reducing manual intervention and the labor intensity. The system cost is low, expansible and easy to install and maintain,has devoted in the actual production, and achieved good effect.
