Cold Model Study of Raceway in COREX Melter Gasifier

In this paper, the method of cold model is applied to study raceway in COREX Melter-Gasifier drawing on the experience of raceway in blast furnace. The influence factors, blasting volume, charging rate which simulates coke consumption, bed packing height have been considered. The results show that the shape of raceway is ellipsoidal and blasting volume, charging rate, bed packing height have effect on raceway. The raceway penetration depth and raceway height expand with increasing blasting volume and charging rate. However, the size of raceway decreases with increasing bed packing height.
