Koppers-Totzek gasifier for powdery coals

Composition of raw gases from Koppers-Totzek process 

In addition to the two combustors introduced briefly above, researches and development on the application of gas-continuous impinging streams to combustion has been carried out since the 1970s, e.g., the investigations made by Goldberg and Essenhigh [ 146], Ziv etal. [12], Goldman [147-149] and Liu et al. [150]. Mostly, these works involve experimental studies and model analyses, and mainly aimed at the improvements of combustor structure and the arrangement of burners in order to increase combustion efficiency. Most of the experimental combustors employed were very small and their application seems far from practical.
