Executive Summary

Bottom heating approach for glass melting offers potential benefits of higher efficiency and lower emissions compared to the conventional surface fired melters with burners above the bath surface. Recent advances in the enabling technologies such as burners, controls, heat recovery and refractive materials have led to reactor, combustion products of coal oxy combustion are bubbled through the three phase re-circulating tank reactor. The turbulence generated by rising bubble column would result in rapid heating and mixing of the charge resulting in fast melting and homogeneous composition of the product. Detailed understanding of such two-phase gas liquid flows is imperative for developing efficient multi-phase reactors through precise control of mixing and reaction kinetics. The bubble column, without any phase change, is a good apparatus for an elementary experimental study and numerical modeling of such flows.
