  1. 1. Theoretical examination of temperature distribution in an electrical furnace by the study of transient heat conduction effects

    University essay from Uppsala universitet/Materialteori

    Author : Judith Bösenecker; [2023]
    Keywords : sintering; heat transfer; transient heat conduction; sintring; värmeöverföring; transient värmeledning;

    Abstract : The company Kanthal produces electric heating elements that require high temperature treatment in one production step. In this process step, called sintering, the amount of heat received by the sintered material is in direct correlation to the product’s outcome. READ MORE

  3. 2. Impact of calcination temperature and time on quicklime slaking reactivity

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Erik Björnwall; [2021]
    Keywords : Lime slaking reactivity; limestone calcination; Calcium carbonate; SEM;

    Abstract : In this master thesis work calcination parameters' impact on the resulting quicklimes slaking reactivity is investigated. This is done by calcination of three different sedimentary limestones in an N2 atmosphere according to a design of experiment matrix. The limestones are from Wolica Poland, Slite Sweden and Jutjärn Sweden. READ MORE

  4. 3. Parameter study of a muffle furnace performance on powder heating using numerical multiphysics simulation with COMSOL

    University essay from KTH/Materialvetenskap

    Author : Emil Stålnacke; [2015]
    Keywords : muffle furnace; syngas; biomass; natural gas; parameter study; comsol; powder metallurgy; heat transfer;

    Abstract : The muffle furnace main purpose is to anneal the rough sponge iron powder transported through it, which is done by burning natural gas. Heat is absorbed by the muffle and is transferred to the bed of sponge iron powder. READ MORE

  5. 4. Exposure studies of refractory materials for biomass gasification

    University essay from Institutionen för tillämpad fysik och elektronik

    Author : Markus Carlborg; [2013]
    Keywords : Gasification; biomass; high alumina refractories; alkali; slag;

    Abstract : Gasification is a technology mostly used to convert fossil feedstock to syngas. Biomass could be used as a feedstock instead but that puts different demands on, among other things, the materials in these reactors. READ MORE

  6. 5. The inter- and intra-specific variability of charcoal traits in boreal ecosystems

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Sophie Charlotte Casetou; [2012]
    Keywords : Charcoal traits; Sorbus aucuparia; Betula pendula; Pinus sylvestris; Fire conditions; Interaction effects;

    Abstract : Wildfire-produced charcoal has been shown to influence key soil ecological processes. However, few studies have considered the role of interacting variables in describing the wide variability of charcoal ecological traits under natural und semi-natural conditions. READ MORE
