Comparison of Heated Charateristics of Smelting Experiment Furnace Wall Using Geothermometer and Cluster Analysis Method of XRD Data

Abstract

In this study, 91 samples were collected by layer, direction, and point from the smelting experiment furnace wall, and XRD analysis was performed. These data were compared with the geothermometer method and the cluster analysis method to determine how to effectively interpret heated characteristics. As a result of comparing the heated characteristics of the 1<sup>st</sup> to 4<sup>th</sup> floors, its showed the same results for both methods because of heated by high temperatures in the 1<sup>st</sup> and 2<sup>nd</sup> floors heated. However, in the data from the 3<sup>rd</sup> and 4<sup>th</sup> floors, it was difficult to interpret the difference in heat temperature depending on the direction using the geothermometer method, but the cluster analysis method was able to effectively confirm the pattern of heat spreading from the center to the outside of the furnace wall. As a result, the cluster analysis method can reduce errors that may appear due to mineral identification in the process of estimating heat temperature using the geothermometer method and there is an advantage in that the temperature distribution within the furnace wall can be further refined.
