The materials input to the DC furnace were ilmenite, anthracite, graphite electrode and nitrogen, and the output were titanium slag, pig iron, offgas and dust.
Molar enthalpy of each element and compound of input and output materials are shown in Table 1.
Energy of input materials equals to total energy of output materials and heatloss of the whole DC furnace system.
Because of water existing in raw materials and feeding by shielding of N2, there were contain a little of H2 and N2 in offgas.

Air drying is the way of drying under the pneumatic conveying by scattering the granular solid materials in the high-speed heat flow.
In this process, with the effect of heat and mass transfer, the moisture in the materials is vaporized[1].
Air drying is suitable for processing the materials which is small in size and whose drying process is mainly controlled by surface gasification[2].
