The paper is devoted to the development of the concept of dual-bed internal circulating fluidized bed (ICFB) gasifier. The concept is also known as fast internal circulating fluidized bed (FICFB) or dual fluidized bed (DFB) gasification and refers to the promising gasification process basing on two interconnected reactors. In an ICFB process developed at JRC-IE Petten, the highly endothermic gasification reactions taking place in the fluidized bed are supported by heat and material exchange from the riser column (combustor) operating in pneumatic transport mode. In contrast to other designs, both reactors are integrally coupled and the riser is coaxially immersed in the gasifier. The obvious advantages of this approach such as excellent heat transfer and overall compactness are accompanied by certain drawbacks such as complication of the facility and problems with separation of gases between reactors. The paper reports on the design of the ICFB gasifier and the modifications leading to improvements in its general operating features. Some preliminary results are also provided together with overall operating experiences we gained during the start-up phase of the facility.
