The relationship between α and ηh is not altered by the presence of an adhering layer. However, at high temperatures and for reactive fuels, an adhering layer influences the combustion rate significantly. The fuel combustion process in iron ore sintering can be viewed as occurring in three regimes depending on factors such as fuel size, reactivity and temperature. To investigate the effect of fuel properties on sintering performance, the developed combustion model is integrated into a 2D iron ore sintering model. Good comparisons are obtained between model results and experimental data from laboratory sintering tests. In the study of fuel types, model results indicate that when biomass char replaced coke there was significant lowering of flame front temperature and combustion efficiency, while the speed of the flame front down the bed accelerated. These changes can be explained by the higher reactivity of the biomass char and its physical properties which influence the granulation process – resulting in changes in the thickness of the adhering layer and combustion behaviour. The flow-on effect of this on sintering performance is consistent with reported experimental results by other researchers.]]> Thu 15 Sep 2022 12:37:25 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:21594 Mon 23 Sep 2019 12:25:24 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32889 Mon 23 Sep 2019 12:24:56 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:31473 Mon 23 Sep 2019 11:42:24 AEST ]]>
