Coal Combustion Behavior in New Ironmaking Process of

2017-8-10  The top gas recycling oxygen blast furnace (TGR-OBF) is a new ironmaking process which can significantly reduce the coke ratio and emissions of carbon dioxide. To better understand the coal combustion characteristics in the TGR-OBF, a three dimensional model was developed to simulate the lance–blowpipe–tuyere–raceway of a TGR-OBF. The combustion characteristics of pulverized coal in
