  5. 24. Assessment of bio-based fuel ash effects on magnesia refractory materials in quicklime production kilns

    Författare :Naresh Kumar Wagri; Britt M. Andersson; Markus Carlborg; Markus Broström; Matias Eriksson; Bengt-Johan Skrifvars; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Refractory corrosion; ash slag intrusion; lime kiln; MgO refractory; coal ash; olive pomace ash; biomass fuel; crushing strength; potassium K ; silicon Si .; Materials Science; materialvetenskap;

    Sammanfattning : Limestone is calcined into quicklime in lime kilns at temperatures above 1000°C. Heat is supplied through combustion inside the kilns, which are insulated with a lining of refractory bricks to mitigate heat loss and to protect the kiln from the hot, chemically aggressive, and mechanically abrasive environment.
