摘要
为了使旧锅炉达到节能减排的目标,将燃油锅炉改造为燃烧LNG锅炉进行了可行性分析。针对LNG锅炉的结构特点及工艺要求,以SAMSUNG PLC为核心控制设备,利用WINGPC3.70软件实现LNG锅炉的全自动燃烧、蒸汽压力、液位控制等。主要阐述了该燃烧控制系统的组成和配置,介绍了实现的功能、方法及PLC程序。实践证明,该设计是合理和高效的。
In order to achieve the saving energy purpose of old boiler, the feasibility analysis which oil-fired boiler transformed into LNG - fired boiler was conducted. As for the structural characteristics and technology requirements of the LNG boiler, the SAMSUNG PLC as the core control equipment, the WlNGPC3.70 soft- ware is used to realize automatic burn,steam pressure and liquid level control of LNG boiler. Mainly described the composition and configuration of the combustion control system, and described the functions, methods and PLC program. Proved that the design is reasonable and efficient.
