2-07　Three-dimensional image analysis of coke gasification reaction and size degradation behavior using X-ray CT

Abstract

In a blast furnace, powder is generated by applying force to deteriorated coke as the gasification reaction progresses. In this study, a medical X-ray computerized tomography was used to photograph coke before and after the gasification reaction and after strength measurement under CRI and CSR conditions. Then, three-dimensional image analysis was used to visualize the same cross-sectional images before and after the reaction and after strength measurement. Using the above method, the relationship between the gasification reaction region of coke and its size degradation behavior at I-type rotational strength was investigated.
