1、摘要:过热温度是各种工业锅炉设备的重要参数。如果过热蒸汽温度过高,则过热器容易损坏,也会使汽轮机内部引起过度的热膨胀严重影响生产运行的安全;过热蒸汽温度偏低,则设备的效率将会降低,同时使通过汽轮机最后几级的蒸汽湿度增加,引起叶片的磨损。因此,必须控制过热器出口蒸汽温度。锅炉过热蒸汽温度的控制任务,就是为了维持过热器出口蒸汽温度在允许的范围内,并保护过热器管壁温度不超过允许的工作温度。本课题利用智能仪表控制系统,结合组态王监控软件设计人机对话界面,实现锅炉过热蒸汽控制系统设计。通过对现场系统数据的采集处理,在组态王中实现动
2、画显示、报警处理、流程控制、实时曲线和报表输出等功能。同时利用智能仪表控制系统,在所设计的组态王监控界面中,进行相关仪表调校和控制器参数整定。最后向用户提供锅炉过热蒸汽控制系统的动态运行结果。关键词:过热蒸汽温度;智能仪表;组态王Abstract:Superheatedsteamtemperatureisavarietyofimportantindustrialboilerequipmentparameters,intheproductionprocess,theentirepathofsoftdrinkisthehig
