SUMMARY:TACOS - Towards a zero CO2 sintering
DESCRIPTION:In order to allow steelmakers to comply with ever stringent environmental constraints, TACOS project aims at evaluating solutions bringing significant decrease of CO2 with consequently decrease of others main pollutants (a.o. NOx, SOx, VOC’s, dioxins and dust emissions). Following alternative heat inputs are investigated :
I.	Alternative solid fuels with or without pre-processing’s;
II.	Waste gas recirculation (case studies are ArcelorMittal Fos, selective lay-out and Tata Steel IJmuiden, non-selective lay-out);
III.	Combustible gases for injection at strand surface;
IV.	High temperature fumes produced in an external combustion chamber.
Combinations of these solutions will also be tested to reached a replacement of 100% of the solid fuel.

For evaluation of the impact of these solutions on sintering process performances and emissions, tasks consists in modelling work (mathematical model), lab trials, sinter pot trials and industrial measuring campaigns and trials. 

These solutions have significant impacts on Blast Furnace process, so a special focus is also placed on their impact on sinter quality (especially on its vertical segregation) and BF performances. For that purpose a wide set of complementary tools not use in usual industrial practice is available amongst the project partners.

At this stage of the project, a replacement rate of the solid up to 80% was tested for the selected alternative solid fuels (pyrolyzed biomass) without significant impact on sinter quality and productivity. Based on the pot trials results, industrial trials will be performed in ArcelorMittal Gent. Blast furnace gas injection at sinter strand surface was tested up to 10% replacement of the solid fuel while the hot fumes injection at strand surface allowed to reach 35% with limited productivity drop.

This research is funded by the Research fund For Coal and Steel (RFCS), project # 847322-1, June 2019 to June 2023.
