ESTIMATION METHOD AND ESTIMATION DEVICE OF IN-FURNACE TEMPERATURE DISTRIBUTION

摘要

PROBLEM TO BE SOLVED: To provide an estimation method of an in-furnace temperature distribution, which estimates an entire in-furnace temperature distribution from the temperature measurement by a limited number of temperature sensors.;SOLUTION: An estimation method of an in-furnace temperature distribution includes a measurement step (step S1) of acquiring temperature information at specific positions in the in-furnace height direction of a formed coke production facility by temperature sensors, a population fabrication step (step S2) of fabricating a population containing a plurality of physical models as members by changing parameters in the physical models, a weighted average calculation step (step S3) of calculating weighted averages of predicted values in temperature distributions in the in-furnace height direction by the plurality of physical models, a coincidence degree calculation step (step S4) of calculating the degrees of coincidence between the predicted values in the temperature distributions in the in-furnace height direction by the plurality of physical models and the temperature information at the specific positions in the in-furnace height direction, and a weight renewal step (step S5) of renewing the weights of the weighted averages by using the degrees of coincidence calculated by the coincidence degree calculation step (step S4).;COPYRIGHT: (C)2013,JPO&INPIT
