2019-7-15  Coal is a natural, complex structural energy material. During the process of combustion or explosion, coal powder undergoes devolatilization, volatile gas combustion, fixed carbon combustion, ash melting, and ultimately forms non-combustible residues. The physical and the chemical characteristics of the coal powder changes greatly.

Energies Free Full-Text Gasification Characteristics

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. The gasification reaction characteristics of the UPC with CO2
