Fig. 1: Block diagram of the process of Syngas production from waste gasification. What is Gasification? Gasification is a partial thermal oxidation resulting in a high proportion of gaseous products (CO 2, H 2 O, CO, H 2, and gaseous hydrocarbons), small amounts of carbon (solid product), ash, and condensable compounds (tars and oils).

The three main WtE processes (incineration, gasification, and pyrolysis) are reviewed in this chapter along with design conditions, different reactor configurations used, and air pollution...

block flow diagram (BFD) • The gasifier is operated at a temperature of >1300 degC to ensure melting all the slag. • Heat is recovered from the syngas stream after a partial quench. • The FT unconverted gases are recycled back to the R-GAS gasifier where they are co-injected with the solid feed. • Carbon Utilization is ~37% : Quench and
