Coal explosibility affects the safety during the injection of coal in the BF. Reactivity – The reactivity of coal refers to reacting ability of coal with carbon dioxide (CO2) or water vapour (H2O) under certain conditions. After pulverized coal injection in the BFe, part of the unburned coal (char) reacts with CO2 while ascending with the gas.

Coal dust is a hazard. Spontaneous combustion is a real possibility, and once fire breaks out it can be hard to control. Guard against the risk with a coal mill gas analysis system measuring the carbon monoxide levels and giving a warning before they become dangerous.
