Numerical study on entrained-flow gasification performance using combined slag model and experimental characterization of slag properties

A steady-state model has been developed to describe the flow and heat transfer characteristics of the slag layer coating the reactor wall during dry-feed solid fuel gasification. The model is firstly tested as a stand-alone tool and secondly, coupled with a CFD-based reactor model. Comprehensive measurements of the slag properties substantiate the modeling results. In order to demonstrate the wide range of the model, two different slag types — a...
