One of the targets of the SCOPE21 process was to enhance the environment around coke ovens. In this process, the charging coal was preheated to about 380℃ and charged into the coke oven. Because the fine coal tends to disperse at high temperature, it was necessary to convey and charge into coke ovens with closed system. So that, the plug transport system was tested in order to clarify the properties of the transportation and to find the design parameter by the fundamental transport test and the combined element bench scale test. The transport system of pilot plant was designed based on the results, and the test was carried out. It was confirmed that the properties of the transportation and the design parameter are appropriate. Moreover, the charging property of the preheated coal into a hot coke oven chamber was made clear, and it was confirmed that the plug transport system provides smokeless and safe charging of preheated coal.
