中文摘要	Accurate models are needed for advanced thermal control systems of utility boilers due to the complexities and time-variations of the boiler. An adaptive model for utility boilers was developed using the Kriging estimation method based on spatial statistics, a non-parametric method in which the unbiased optimal estimate for the unknown functions is obtained without model structure selection or training. This paper also presents an adaptive Kriging model that adjusts the sample space in real-time. The predictive capacities of artificial neural networks (ANN) and the Kriging model were evaluated by comparing the predicted NO/sub x/ emissions of utility boilers with data from a series of field measurements, with both interpolation and extrapolation. The results from five groups show that the average predictive error of the ANN model of 11. 59% is reduced to 3. 49% by the Kriging model.
