    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.

  3. 2. Refractory corrosion in biomass gasification

    Författare :Markus Carlborg; Rainer Backman; Dan Boström; Ragnhild Aune; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Refractory corrosion; slag; biomass; gasification; Materials Science; materialvetenskap;

    Sammanfattning : To stop the net emission of CO2 to the atmosphere, we need to reduce our dependency of fossil fuels. Although a switch to a bio-based feedstock hardly can replace the total amount of fossils used today, utilization of biomass does still have a role in a future in combination with other techniques.

  7. 5. Microstructure and Mechanical Properties of Plasma Atomized Refractory Alloys

    Författare :Marina Ciurans Oset; Farid Akhtar; Johanne Mouzon; Dariusz Jarzabek; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasma atomization; spherical powder; tungsten carbide; high entropy alloy; refractory; Engineering Materials; Materialteknik;

    Sammanfattning : Plasma centrifugal atomization is a method widely used in the production of spherical powders of metals and alloys with relatively low melting points. A novel plasma centrifugal atomization process suitable for high melting point materials (i.e. 3500 ᵒC and above) was developed by Metasphere Technology AB, currently Höganäs Sweden AB. LÄS MER
