Types of Gasifiers
Although there are various types of gasifers (gasification reactors), different in design and operational characteristics, there are three main gasifier classifications into which most of the commercially available gasifiers fall. These categories are as follows:
Commercial gasifiers of GE Energy, CB&I E-Gas™ and Shell SCGP are examples of entrained-flow types. Fixed-or moving-bed gasifiers include that of Lurgi and British Gas Lurgi (BGL). Examples of fluidized-bed gasifiers include the catalytic gasifier technology being commercialized by Great Point Energy, the Winkler gasifier, and the KBR transport gasifiers. For more specific information on these gasifiers and others, follow the links for the bulleted gasifier types above.
NOTE: Although specific gasifiers named above are described in detail throughout this website, it is realized that other gasification technologies exist. The gasifiers discussed herein were not preferentially chosen by NETL.
