摘　　要：为提高电站锅炉运行经济性和安全性,提出一种基于热力学模型的电站锅炉对流受热面积灰状态实时监测方法,并利用其监测结果对吹灰系统进行优化。根据这一方法开发的实时监测系统已在太原第一热电厂11号炉应用并获得成功。该监测方法具有简单、运行可靠、初投资少等优点,开发的软件具有良好的用户界面。In order to raise the economics and safety of utility boilers,a thermodynamics model-based real-time monitoring method of ash fouling on the convective heating surface of utility boiler was put forward,and the monitoring results could be used to opti-mize the soot-blowing system.The real-time monitoring system,developed on the basis of this method,has been successfully ap-plied on No.11boiler of Taiyuan No.1Cogeneration Power Plant.This method features simple,reliable and low initial investment etc.,and the developed software has good customer interface.
