摘要
针对现有的煤粉锅炉燃烧系统存在供粉量不均匀、结渣、燃烧不充分和负压不稳等问题,以一台20 t的导热油炉为控制对象,提出了一种煤粉锅炉燃烧系统集散控制系统的设计方案;详细介绍了该系统的硬件及软件设计。测试结果表明,导热油炉运行稳定,各项技术指标符合设计要求,实现了煤粉锅炉燃烧系统的优化控制。
In view of problems of uneven powder supply,slagging,inadequate burning and unstable negative pressure existed in current combustion system of pulverized coal boiler,the paper proposed a design scheme of DCS of combustion system of pulverized coal boiler by taking a 20 t heat-conduction boiler as control object.It introduced design of hardware and software of the system in details.The test result showed that the heat-conduction boiler runs stably and each technical index accords with design requirements,which realizes optimal control for combustion system of pulverized coal boiler.
