A mathematical model for the prediction of the performance of a glass furnace is described. It comprises sub-models for the combustion chamber, feed stock melting (batch), and the glass tank flow. The first sub-model which incorporates physical modelling for the lifted turbulent diffusion flames, soot formation and consumption, and the thermal radiation is given emphasis herein. The whole mathematical model is applied to an end-port regenerative furnace for both gas and heavy oil firing.
