| The predicting model based on the GA-BP network was established to meet the requirement for the on-line prediction of power coal quality and combustion characteristics by the digital information control system. The model was adopted to determine the relationships between qualities of the blended coal and its components and was established for predicting the quality indices of the coal, such as the moisture content Mad, ash content Aad, volatile content Vad and heating value Qnet, ar. Based on the quality indices Mad, Aad, Vad and Qnet, ar.of each coals and the mixture ratio X, the quality indices Mad, Aad, Vad and Qnet, ar and the combustion characteristic parameter of Ti、C, WI of the blended coal can be directly predicted by the model. The prediction results showed that the model is feasible and effective. |
