ABSTRACT = {Iron ore sintering is a pre-treatment technology by which ore fines are converted into porous and permeable sinters, which are the used in blast furnaces. This process can be adversely affected by air leakage phenomena of
various types. As experimental measurements are relatively difficult and often scarcely reliable, here a theoretical
model based on typical fluid-dynamic concepts and relationships is elaborated. Through the analysis of two
extreme cases, namely, those in which leakage is due to a small hole or a full rupture, a generalized hole-bed model is introduced, which for the first time also includes a complete bed permeability equation and can deal with
different leakage position conditions. The results show that the model can evaluate the influence of leakage on
the system at one time and be used to calculate the flowrate and pressure drop. Notably, the obtained results
are within a 15% deviation with respect to available experiment values, used for comparison.},
