Abstract

The behavior of the inclined oxygen jet was theoretically analyzed and the post combustion ratio was calculated after combining a previous experimental data with a theoretical model. Equations of continuity, conservation for momentum, enthalpy and gas species inside the jet were derived from quasi one-dimensional assumption. The relation between the reaction rate and the theoretically calculated physical quantities is obtained statistically from data in real converters. The model shows that the optimal secondary oxygen flowrate is determined by the lance height, nozzle diameter, and nozzle angle in order to obtain the maximum post combustion ratio.
