Abstract

To address the challenge of predicting SO2 concentration under quick load change conditions for circulating fluidized bed (CFB) units

from the principles of combustion

the mechanisms of SO2 generation and reduction within the furnace were analyzed

and models were constructed for the combustion of char

dynamic oxygen balance

and reactive limestone. Based on these models

an SO2 concentration prediction model was established. The model took coal feed rate

bed temperature

total air flow

and limestone feed rate as input variables. By integrating multidimensional correlation analysis

key intermediate parameters such as char combustion rate

dynamic O2 concentration

and reactive limestone were introduced as extended inputs to reconstruct the dataset. The reconstructed dataset was trained using the Kolmogorov-Arnold network (KAN) to build a hybrid input Kolmogorov-Arnold network (HIKAN). The model hyperparameters were optimized using the meta-learning optimizer (MLO)

resulting in the proposed MLO-HIKAN prediction model. Case study results demonstrate that this model achieves high accuracy in predicting SO2 emission concentration under quick load change conditions

providing a new method for the environmentally friendly operation of CFB units.
