超临界直流锅炉给水控制系统的探索性改进

Feed-water Control System Innovation of Super-critical Once-through Boiler

超临界直流锅炉的给水控制系统较为复杂,影响因素繁多。为了使给水控制系统更为灵敏、可靠,并且充分利用众多的实时测量数据,基于多传感器信息融合技术对水冷壁温度和煤质在线分析数据进行了数据融合,融合信息对直流锅炉的给水控制系统进行重构和优化,从而使直流锅炉的给水控制系统更为有效。

Feed-water control system of supercritical once-through boiler is complex and interfered by so many factors. In order to improve control system＇s efficiency and utilize on-line data, temperatures of water wall and data of on-line coal analyzing are fused based on the multi-sensor information fusion, the fused information is used to control the feed water flow in the supercrifieal once-through boiler, so the operating reliability is strengthened.
