METHOD FOR CHARGING RAW MATERIALS INTO FURNACE USING GAS DISTRIBUTION PREDICTING MODEL IN RADIUS DIRECTION OF FURNACE

摘要

PURPOSE: A method for charging raw materials into a furnace using the gas distribution predicting model in a radius direction of the furnace is provided to more accurately obtain gas distribution in the radius direction of the furnace by considering influence of the temperature of a gas on viscosity and density of the gas in the step of calculating gas distribution in the radius direction of the burden distribution control model. CONSTITUTION: The method for charging raw materials into a furnace using the gas distribution predicting model in a radius direction of the furnace comprises the steps of obtaining a temperature distribution of gases calculated by the distribution of gases of the results obtained from the step of calculating the distribution of gases in a radius direction of a furnace; a temperature deviation calculation step of judging whether or not a temperature difference according to the obtained temperature distribution of the gases is smaller than the range of standard deviation; and a correction step of correcting so that the temperature difference is smaller than the range of standard deviation, thereby determining a charging mode of the furnace using the gas temperature distribution predicting model in a radius direction of the furnace corrected in the correction step.
