目前已开发出一种采用图象处理技术预测电站燃煤锅炉未燃碳的方法.这种方法包括有图象处理单元和炉膛模型单元,通过前者可以获得燃烧火焰的温度分布情况.通过后者则可按给煤率、空气量、煤的化学含量和灰分计算出从燃烧器到炉膛出口碳的还原动态特性.日本东北电力公司仙台电站的试验研究表明:未燃碳的预测误差可降低至10%. At present, a method for predicting the unburned carbon of a coal-fired boiler by using an image processing technique has been developed. The method includes an image processing unit and a hearth model unit, through which the temperature distribution of the combustion flame can be obtained. The kinetic characteristics of reduction of carbon from burner to furnace exit can be calculated according to the feed rate, air volume, chemical content of coal and ash content.The experimental study of Sendai Power Plant of Tohoku Electric Power Company shows that the prediction error of unburned carbon can be reduced to 10%.
