Abstract

Coal is an important energy resource for meeting the further demand for electricity, as coal reserves are much more abundant than those of other fossil fuels. But, coal utilization technology produces carbon dioxide more than other fossil fuels, because of the higher carbon content of coal. For the control of the global warming problem, it is required to develop a new technology for the reduction of carbon dioxide emission from coal-utilized power stations. To reduce carbon dioxide emission, it is very important to develop a new technology of high efficiency power generation system and utilize biomass energy of carbon neutral. For the further reduction of carbon dioxide, the removal and storage technology is an effective one. It is necessary to apply the smart process of powder technology for the development of coal utilized power generation system of new type including a high efficiency power generation system and carbon dioxide removal type power generation system. For the utilization of biomass energy, it is very important to develop the smart technology for the handling of biomass like drying, carbonizing, pulverizing and conversion technology. In this paper, many technologies for the powder handling related to the high efficiency coal utilized power generation, biomass utilization and carbon dioxide removal power generation are introduced. Furthermore, the present level of these technologies and the development tendency for the future are surveyed. Keywords: coal utilization, carbon dioxide, biomass, low rank coal, high efficiency power generation.
