摘要
基于回转式空气预热器受热面积灰程度与烟气侧流动阻力间的依赖关系及其相关影响因素 ,提出了折算压差的概念 ,推导了积灰监测的计算模型。根据发电机组计算机数据采集系统 (DAS)烟气侧实时检测的烟气侧压差等参数 ,实现了 3 0 0 MW燃煤电站锅炉回转式空气预热器积灰状态的在线监测。图 1参
Based on the dependence of gas flow drag force on ash accumulation for rotary air heater, the converted pressure drop is proposed and ash monitoring model is derived. On line ash monitoring of the rotary air heaters for a 300MW coal fired utility boiler has been realized by processing the relevant operational data acquired from the DAS. Fig1 and refs 3.
