説明

Status of research and development of advanced coal-utilized power generation technologies such as pulverized coal combustion and integrated coal gasification combined cycle (IGCC) power generation systems were reviewed and discussed in this paper. It was confirmed in the pulverized coal combustion system that the advanced low NOx combustion technology with a new type low NOx burner effectively reduced NOx emission and moisture evaporated from low-rank coal significantly affected combustion characteristics of bituminous coal blended with the low-rank coal. It was also revealed in the IGCC system that simultaneous evaluation of gasification efficiency and molten slag behavior was essentially important to maintain stable operation of the system. Throughout the research activities, it is found that a numerical simulation was a key technology to assess and optimize design and operation of major components such as coal combustion boiler and coal gasifier in the systems.
