Coke production by chamber ovens has a long history and efforts are being continued to make the manufacturing process efficient and to preserve the environment. In this production by this method, however, it is hardly possible to obtain direct information during coal carbonization. Since the elements that compose coal and coke are carbon, hydrogen, oxygen, etc. and are similar to those of the human body, authors has developed a coke oven that permits the direct observation of the coal carbonization process using a soft X-ray computerized tomography (CT) apparatus used in medical treatment. The following phenomena can be observed as images by the coke oven for the CT method: · Changes in the bulk density of charge coal (including the difference in the water content) ·Width of the plastic layer and movement of the plastic layer in the coke oven chamber ·Expansion and shrinkage of the charge in the coke oven chamber · Initiation and growth of cracks.
