Description |
A first principle based mathematical model has been developed to characterise the effect of
total liquid hold-up on the bosh silicon distribution behaviour in the dripping zone of a
blast furnace. Two specific cases of hold-up behaviour have been investigated, namely,
hold-up in the absence and in the presence of counter current gas flow conditions. The
model exemplifies coupled phenomenon of chemical kinetics, transport processes and
liquid hold-up to characterise the silicon behaviour in the dripping zone. The present modelling
investigation shows that the bosh silicon level diminishes with the enhanced liquid hold-up in the dripping zone. Further, the influence of counter current gas flow on the hold-up is not significant. However, it has been observed that the liquid phase temperature reduces with increased liquid hold-up in dripping zone under steady state operating conditions. The model predictions of bosh silicon distribution have been validated with the published literatures (bulk values) and found to be in good agreement.
