Abstract
Enormous amounts of water and energy are lost by scrubber utilization for furnace exhaust gas washing during direct iron reduction process. Hence, the aim of the current research is design and construction of a system which could be employed instead of scrubber within direct iron reduction process considering the equipment size constraints.To this end, the substitute system was manufactured after dimensional analysis and simulation of lab model compared to the prototype regarding the implementation limitations. The model has been tested in different operating conditions and empirical relations have been extracted for general analysis of direct iron reduction process. The case study here is...
