CFD study on the effect of velocity and temperature toward the performance on partial combustion unit

In the iron and steel making process,Direct Reduction Plant (DRP) is the most important components which are consist of Partial Combustion Unit(PCU).PCU take place in between the process gas heater and the oxides removal reactor.The PCU consists of one transfer line and two oxygen lances.On the oxyg...
