Features of Gasification Systems

In the practical realization of gasification processes a broad range of reactor types has been and continues to be used. Although the usual classification is by bed type, there are other features to be considered and many of these can be selected independently of the bed type. The most important of these will be discussed as follows  

Typical processes Lurgi BGL Winkler, HTW, CFB KRW, U-Gas Shell, Texaco, E-Gas, Noell, KT 

Acceptability of fines Limited Better than dry ash Good Better Unlimited 

Acceptability of caking coal Yes (with stirrer) Yes Possibly Yes Yes 

Other characteristics Hydrocarbons in gas Hydrocarbons in gas Lower carbon conversion Lower carbon conversion Pure gas, high carbon conversion
