Ebara' s ICFG (Internally Circulating Fluidized-bed Gasifier) is an innovative technology, which makes it possible to recover valuable producer gas from various kinds of low-grade feedstock, such as biomass or waste materials. In order to realize efficient energy conversion, it is important to optimize the way to provide the heat necessary for the gasification and/or pyrolysis, the way to control the generation of char and tar, and the way to use their calorific value effectively. ICFG can be a solution for the problems of conventional gasifiers in the senses mentioned above. ICFG's basic concept can be seen in its unique structure. Its furnace is separated into two chambers, typically called gasification chamber, and combustion chamber. While those two chambers literally play different roles, gasification and combustion, they are linked with each other by the effect of internal circulation of bed materials. An effective transfer of heat and materials can be realized by this, and ICFG's various superior features are generated by this basic concept. ICFG has an advantage over conventional high-temperature gasifier in its cold gas efficiency and calorific value of producer gas. Various ways to use ICFG's producer gas are described.
