超临界机组热力系统腐蚀与氧化在线监测系统研究

Research on Online Monitoring System for the Corrosion and Oxidation Process in Thermal System of Super Critical Unit

通过测量发电机组水汽系统中溶解氢的含量对热力系统腐蚀与氧化过程进行在线监测,以此来研究金属材料高温腐蚀与氧化的规律。利用最新研制的在线溶解氢分析仪表,实时观测机组的运行状况,并通过对采集数据的分析,来判断氢含量的各种影响因素。

In this paper,by measuring the content of dissolved hydrogen in steam system of power plant boiler,we monitor online the corrosion and oxidation process in thermal system and study the law of high temperature corrosion and oxidation of metal materials. We observe the operation condition of the unit in real-time by a new online hydrogen monitor. Through the analysis of the collected data,we can estimate the various factors affecting hydrogen content.
