Major gasifiers for IGCC systems

Dr. David Gray,    Noblis (Retired)


This chapter summarizes global coal gasification systems that are suitable for Integrated Coal gasification Combined Cycle (IGCC) applications. Not all global gasification systems are covered in this chapter only those considered, by the author, to produce synthesis gas that, after cleaning, is suitable for utilization in gas turbines for electric power generation. Gasifier characteristics of entrained flow, fluid bed, transport gasification, and fixed bed gasification are discussed. A brief history of the gasification development is discussed followed by a detailed description of the process. Gasifier performance including expected synthesis gas composition, ...
