基于组态软件的供暖锅炉监控系统设计摘 要 工业锅炉是采暖供热系统的核心设备，它的主要任务是安全可靠、经济有效地把燃料的化学能转化为热能，进而将热能传递给水，生产出满足需要的蒸汽或热水。本文主要介绍的是通过组态软件（MCGS）做成的一套锅炉监控系统。大家都知道我们可以把锅炉分为三个相对独立的环节去控制：燃烧系统的控制，汽包液位的控制，过热蒸汽温度的控制。本文也采纳了这样的分环节控制的方法。首先，用炉膛内的压力与饱和蒸汽的压力组成串级控制系统去控制燃料的供给量，继而控制了燃烧系统。当然为了安全起见我们还必须用一个压力传感器去测量炉膛内的压力。其次，用饱和蒸汽的温度和汽包的水位组成串级控制去控制给水量，继而控制汽包的水位。最后，用过了减温器的蒸汽的温度与过热后的蒸汽的温度组成串级控制去控制减温水的供给量，继而控制过热蒸汽的温度。该系统具有数据采集，实时控制，在线查询等功能，同时能够通过一些简单的传统控制（PID 控制）对其进行相对稳定的控制。本文针对过路系统三个环节中的每个环节的单独控制（燃烧系统控制，汽包液位控制，过热蒸汽温度控制），得到了比较稳定的锅炉系统，同事又对其进行了较为良好的监控。关键词：组态软件；锅炉；串级控制；安全Configuration Software-based Monitoring System of the Boiler AbstractIndustrial boiler heating system is the core of heating equipment, its main task is that have a safe, reliable, cost-effective way to make fuel chemical energy into heat energy, then the heat transfer water to produce steam or hot water to meet the need. The safe operation of the boiler is now the focus of the boiler system, we should have a complete set of monitoring equipment to monitor the boiler, it can be timely to get rid of a number of security incidents. In this paper, it is a boiler control system made by the configuration software (MCGS). We all know that we can divide the boiler control system into three relatively independent parts to control: combustion system control, drum level control, temperature control of superheated steam. This a...
