As a part of a collaborative undertaking, Boliden, E.ON and Chalmers College has confirmed the potential for iron sand to be a promising substitute for conventional silica sand in fluidised mattress combustion (FBC).
The undertaking, funded by the Swedish Vitality Company, Boliden and E.ON, goals to discover how iron sand can contribute to a extra sustainable and environment friendly combustion course of.
Iron sand is a glassy iron silicate combination consisting of granulated slag, extracted as a by-product from Boliden Rönnskär’s copper manufacturing. New outcomes from a two-week marketing campaign in Chalmers semi-industrial CFB-type analysis boiler confirmed that iron sand not solely can substitute silica sand but in addition enhance combustion outcomes, with decreased CO and NO emissions, Boliden said.
Going ahead, the initiative will consider iron sand as mattress materials in full-scale waste incineration and to design a enterprise mannequin for the fabric’s introduction on a business scale.
Magnus Rydén, Professor in Vitality Conversion at Chalmers, mentioned: “This collaboration brings collectively the experience of academia, trade and power sectors to discover progressive options for a sustainable future – on this case changing a non-renewable useful resource like pure sand with a round bi-product from the trade. Partnerships like these are nothing however important for the trade’s transition.”
Peter Johansson, Supervisor Gross sales Iron Silicates at Boliden, mentioned: “The usage of iron sand as mattress materials in FBC is promising and will provide vital benefits over widespread silica sand. This undertaking highlights the potential for a extra sustainable future within the combustion trade, and we’re excited to take the following steps in direction of business implementation.”
