摘要：在工业迅速发展的推动下，我国的经济水平得到了大幅的提升。锅炉作为最重要的动力机械设备起着不可替代的作用，因此锅炉有着巨大的发展前景，但是我国锅炉的燃烧效率较低，也就使得锅炉的供能不够高效。
    本设计结合力控软件和PLC控制技术对这一问题进行了重点的研究。采用现代计算机技术对锅炉进行优化控制，从而大大提高其燃烧效率，节约一次能源，减少所产生的环境污染，对社会经济和环境质量的提高有很大的意义。通过对锅炉各个部分控制要求的研究，结合参考文献和实际情况设计锅炉的自动控制系统。所研究设计的控制系统可以对锅炉进行集中监测、控制、管理。集中体现在对锅炉燃烧控制、水位汽包控制、过热蒸汽温度控制以及安全系统的控制设计。
    本设计采用S7-300 PLC为核心控制器，同时结合变频器技术、传感器与检测技术以及以太网技术将所有设备构成一个整体，并与其他操作设备建立起良好的通信，对锅炉进行集散控制。通过STEP 7编程软件对PLC进行软件编程，并与力控软件结合，构成对锅炉的实时监控系统。20358

Design of industrial boiler control system
Abstract：With the rapid development of industry, the level of economy has been greatly improved in China. Boilers as the most important power machinery equipment play an irreplaceable role. Therefore, boilers have great prospects. However, in China it is not enough to supply energy because of the low combustion efficiency of boilers.    
   This design focuses on the issue with ForceControl6.1 and the PLC control technology. To raise its combustion efficiency, save primary energy sources and reduce the environment pollution, this paper uses modern computer technology to optimize the control of boilers, which has great impact on the socioeconomic and environment quality. Through the study on the each part of control requirements combined with the references and lots of documentation, it designs an automatic control system of boilers that can be implemented on boiler for centralized monitoring, control and management. It intensively reflects on the control of boiler burning, the control of water level and bubbles, the control of superheated steam temperature and the design of safety inspection system.
   The design uses S7-300 PLC as the core controller. At the same time, it applies distributed control of boilers, combined with the inverter technology, sensors and measurement technique and Ethernet technique to all the devices as a whole. And set up a good communication with other operating equipment. Through STEP 7 programming software for upper computer software programming and combine with ForceControl6.1. It constitutes a true time monitoring and control system of boilers.
