Pulverized coal injected into a blast furnace (BF) burns incompletely in a very limited amount of time. A considerable amount of unburned pulverized coal (UPC) escapes from the raceway to the coke layer. The unburned pulverized coal reacts with CO2 in the coke layer, and this has a very significant impact on the operation of the BF.

Mathematical modelling of pulverized coal furnaces

As it was previously said, pulverized coal goes into the boiler mixed with recir-culating gases at a temperature of 300oC approximately. Preheated fresh air is also introduced. In a first stage evaporation of coal moisture and release of volatiles (pyrolysis) takes place. The latter will be burnt in the gas phase. Then combustion of free
