A NUMERICAL MODEL FOR CHEMICAL REACTION ON SLAG LAYER SURFACE AND SLAG LAYER BEHAVIOR IN ENTRAINED-FLOW GASIFIER

ABSTRACT
The paper concerns with slag layer accumulation, chemical reaction on slag layer surface, and slag layer flow, heat and mass transfer on the wall of entrained-flow coal gasifier. A slag layer model is developed to simulate slag layer behaviors in the coal gasifier. This 3-D model can predict temperature, slag particle disposition rate, disposition particle composition, and syngas distribution in the gasifier hearth. The model is used to evaluate the effects of O2/coal ratio on slag layer behaviors.
