| Abstract: | Aiming at the problems such as lagging, large error, and so on of the existing measurement method for mass fraction of carbon content in boiler fly ash, a Partial Least Squares(PLS)-based prediction model was put forward, based on which analysis and testing on the regression effect of the model have been made upon a large amount of operating(sam ple)data of a power plant.Results show that the method can overcome the multiple correlations among data and is characterized by high prediction speed and calculation accuracy. |
