Total costs for carbon injection installation, added to HBC

Catalytic bag filter systems are used in the waste ineinerator sector. Cost data from this application are transposed on basis of the flue-gas volume to be treated, but without taking into account operational parameters such as air-to-cloth ratio. For a depreciation time of 5 years, the investment and operational costs can be estimated at EUR 0.4 - 0.5/tonne molten metal for HBC and EUR 0.9 - 1.3/tonne molten metal for CBC. This priee estimation was nor eonfirmed nor discarded by a catalytic bag filter supplier.

Following collection, the gases may need cooling depending on the dust abatement system used. In the hot blast operation, the heat recovered from cooling may be used for preheating the blast air. 

Several options are possible for cooling the collected gases, including
