The space utilisation values were calculated by mathematical modelling of particle dissolution and bubble rising in a model melting channel. It has been found that for a given sand-dissolution time and bubble-growth rate, the space utilisation value was determined as the ratio between transversal and longitudinal temperature gradients. The highest space utilisation values for both dissolution and bubble removal are reached when both types of temperature gradients are combined and the transversal temperature gradient is 5-10 times higher than the longitudinal one. A cautious application of optimal conditions in the model glass furnace leads to an increase in the furnace space utilisation.
