The Air Blown Gasification Cycle (ABGC) (formerly known as the British Coal Topping Cycle) is a high efficiency low cost system for producing power with excellent environmental performance. High efficiency is achieved without the complexity associated with other advanced cycles and the technology can be introduced in a modular fashion. Being a simple air blown fluid bed gasifier and combustor combination it is capable of using a wide range of fuels and is particularly suited for dealing with high ash melting point fuels found in areas of the world short of natural gas. An extensive program of pilot plant testing of a variety of fuels is now being completed on the test facility at the Coal Technology Development Division (CTDD) of British Coal as part of a UK program to develop the Air Blown Gasification Cycle. This program is supplying data to produce a design specification for a Prototype Integrated Plant (PIP) of around 90 MWe, and is managed by a consortium, the Clean Coal Power Generation Group. The paper summarizes recent results and operating experience for the pilot plant including fuel behavior studies, research in hot gas cleaning (particulate and gaseous contaminants), and gas combustion experience. The various cost studies undertaken on the ABGC are outlined and compared, including recent studies by EPRI.
