摘　　要：人工智能时代,人工神经网络拥有强大的计算能力、逼近能力、学习能力和动态分析能力,其中,以BP神经网络算法为代表的反向误差传播训练算法最常用,在燃煤电厂各个环节得到了广泛的应用。为了实现超临界燃煤锅炉受热面灰污的预测,本文采用基于BP神经网络预测锅炉低温受热面的清洁因子,从而实现安全、经济、稳定的燃烧。In the era of artificial intelligence,artificial neural networks have powerful computing power,approximation power,learning power and dynamic analysis power.Among them,the back error propagation training algorithm represented by BP neural network algorithm is the most commonly used,and has been widely applied in all links of coal-fired power plants.In order to predict the fouling of the heating surface of the supercritical coal fired boiler,this paper USES BP neural network to predict the cleaning factor of the low-temperature heating surface of the boiler,so as to realize the safe,economical and stable combustion.
