Temperature distribution estimation method and the temperature distribution estimation apparatus

摘要

PROBLEM TO BE SOLVED: To estimate a temperature distribution of an entire inside of a coke production facility from information of a temperature detection means of a limited number with high accuracy.SOLUTION: A CPU 113: generates two or more physical models by changing a value of a physical parameter included in a physical model to estimate a temperature distribution in a vertical carbonization furnace; estimates the temperature distribution in the vertical carbonization furnace using the two or more physical models; estimates a temperature in the vertical carbonization furnace in a position in which a temperature detection means is arranged for the respective two or more physical models using the estimated temperature distribution in the vertical carbonization furnace; calculates adaptation of the estimated temperature and a temperature detected by the temperature detection means for the respective two or more physical models; imparts a weight to each of the respective physical models based on the calculated adaptation; and calculates a value to be obtained by multiplying the estimated temperature distribution in the vertical carbonization furnace by the weight for each of the respective two or more physical models; and calculates the sum of the multiplication values of the respective physical models as the temperature distribution in the vertical carbonization furnace.
