Optimization of flow field to attain high slag rejection efficiency from a cyclone slagging gasifier to retrofit gas/oil fired boilers was experimentally studied by an acrylic cold model gasifier. The air was tangentially introduced at two cross sections, one from upstream of the furnace and the other from downstream to adjust the flow field. To simulate the molten slag formed during combustion/gasification of a pulverized coal gasifier, water spray was introduced into the furnace. The slag rejection efficiency along the furnace wall was compared with those for various flow distributions. Results show that it is possible to optimize slag rejection and flow field by means of regulated operations to such parameters as pulverized coal injection angle, furnace outlet diameter, air inlet conditions and furnace inclination angle.
