Inertization of coal mill circuit and fine coal bins with CO2, N2 or CO2+N2 to replace O2 which promotes spontaneous ignition of fine coal. Vertical roller mills can typically handle an aggregate moisture of up to 20% in raw materials and consumes about 30% less power in grinding. Hence it is commonly preferred for grinding operation in new plants of higher capacities. However,

· These coals besides high moisture content also have high volatile content and low calorific value (CV) with easy spontaneous ignition. High moisture content is the main restraint for the application of lignite coals. Moisture content of coal causes many difficulties during processing, storage, transport, grinding, and combustion.
