Development of advanced coal cleaning process; Kodo sekitan kaishitsu gijutsu no kaihatsu

Abstract

This paper aims to develop a clean coal production process which excellently removes environmental pollutant, is low-costed, and need no particular systems for distribution of products. The result of the development was described paying attention to column flotation which is a technology to high-efficiently select particulate regions, particulate heavy media cyclone, magnetic separation, and the basic design of the process into which those above were integrated. The two-stage selection process, which is an integration of column flotation and particulate heavy media cyclone into the conventional coal preparation equipment, can produce low-ash clean coal at high separation efficiency and also suppress the rise in processing cost. This process was also effective for removal of sulfur content and trace metal elements. The use of clean coal at power plant can be effective for not only the reduction in ash treatment amount, but the aspect of boiler operation characteristics such as heat transfer efficiency of boiler furnace wall, ash related troubles, loads of electrostatic precipitator, loads of flue gas desulfurization facilities. 17 figs., 5 tabs.
