METHOD AND SYSTEM FOR GENERATING BLAST FURNACE OPERATING PREDICTION MODEL ACCORDING TO HYDROGEN-CONTAINING GAS INJECTION

摘要

The blast furnace operation prediction model generation system according to the injection of hydrogen gas according to an embodiment of the present invention is a reaction tube in which a reduction reaction in which hydrogen-containing reducing gas and iron ore react to reduce to reduced iron, blast furnace operation when hydrogen-containing gas is not injected Temperature information corresponding to different heights inside the reaction tube in which the reduction reaction is in progress, controlling the amount of injection of the fuel material and the reducing gas into the reaction tube based on the conditions and the set amount of hydrogen injection and obtaining gas composition information, analyzing the temperature information and the gas composition information to calculate reduction efficiency, material balance and heat balance in the reaction tube, and calculating the reduction efficiency, material balance and heat balance in the reaction tube. Based on the reduction reaction analysis device for predicting the appropriate tuyere blowing conditions and reduction index corresponding to the hydrogen injection amount, and based on the appropriate tuyere blowing conditions and the reduction index corresponding to the hydrogen injection amount, hydrogen during operation of the blast furnace It may include a predictive model generating device for generating a predictive model for guiding the appropriate tuyere blowing conditions and reduction index changes for each blowing amount.
