The blast furnace raceway shows different characteristics with PCR (pulverized coal injection rate). It was found in this study that with the increase of PCR the raceway depth decreases, and the size of birds nest and sometimes with liquid holdup, increases. Oxygen enrichment with co-axial lances was known to be very effective on the extension ...

AbstractPulverized coal is injected into blast furnace tuyeres to reduce coke consumption as well as to reduce hot metal production cost. Knowledge of the combustion behavior of pulverized coal in the blast furnace raceway zone and accumulation of unburnt char are of paramount importance. To alleviate the problem of high computational time of a multidimensional model, a reduced order raceway ...

Simulation of tuyere–raceway system in blast furnace ...

AbstractA uniform distribution of the blast is an important prerequisite of a balanced blast furnace operation, because the blast is the main source of the hot gases that are needed to preheat, reduce and melt iron ores. The supply of hot gas from the raceways is not necessarily uniform along the furnace periphery, but depends on flow resistances encountered on the individual bustle main ...

Prediction of Raceways in a Blast Furnace | Energy ...

In a blast furnace, preheated air and fuel (gas, oil or pulverized coal) are often injected into the lower part of the furnace through tuyeres, forming a raceway in which the injected fuel and some of the coke descending from the top of the furnace are combusted and gasified.
