Abstract：In the current study， a stove control model was proposed based on the mechanism model and the identification model to study the variation of the instantaneous input and output in the stove combustion process. In the present model， the mechanism model was first established to calculate the input and output during the combustion operation of stove， then the identification model was developed and verified using plant data， finally both models were then comprehensively applied to generate a new input and output model. Simulation analyses were performed to investigate the input-output relationships in these three models. Results show that the comprehensive application of the first two models can better control the stove combustion process， damp the disturbance slowly to achieve full combustion， realize the longevity under high air temperature， and thus make the hot blast stove more energy-efficient and environmentally friendly.
