The calculate formula premise of the residual life of boilerconvection heating surface is pointed out, and the cause of heating surface wearing due to the quality decline of coal is analyzed.
Fouling Monitoring Modeling System based on the BP neural network for boilerconvection surfaces is presented in this paper.
采用多层前向型神经网络，对电站锅炉对流受热面的实时污染状况建立了监测模型。
