ABSTRACT
The ways of using biomass for energy purposes are predominantly predetermined by its physical and chemical properties. The replacement of coke powder as agglomeration fuel, although so far only partial, is becoming an issue that has been ever more topical. The aim is primarily to circumvent the carbonisation process and thus significantly reduce the cost of treatment of fuel raw materials, which ultimately translates directly into the price of agglomerated charge for the blast furnace process. The biomass is characterised by the relatively high and frequently variable water content, which significantly affects the energy properties of biomass fuel. The various types of biomass have much higher content of volatile matter than coke powder. The oil extraction moulds as residues from biofuel production were considered unsuitable for agglomeration due to the high volatile content. The production of ferriferous agglomerate also requires an analysis of thermodynamic and kinetic conditions of the process.
