  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

  5. 4. High temperature corrosion on heat exchanger material exposed to alkali salt deposits

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

    Author : Kajsa Persson; [2015]
    Keywords : high temperature corrosion; alkali salt; deposits; heat exchanger;

    Abstract : Power generation through decentralized small scale CHP would facilitate the use of biomass as an energy source, with the externally fired gas turbine (EFGT) being a promising technology due to its high electrical efficiency. In an EFGT hot flue gases are heat-exchanged with an air cycle, driving the turbine. READ MORE

  6. 5. Maximum element temperature for Kanthal Super 1800S in flowing nitrogen atmosphere with low content of oxygen

    University essay from Materialvetenskap

    Author : Petter Persson; [2010]
    Keywords : MoSi2 Mo5Si3 Oxidation High Temperature Heating element;

    Abstract : Abstract The behavior for MoSi2 based high temperature heating elements for resistive heating has been examined in elevated temperature and low oxygen content environment. MoSi2 spontaneously forms a protective SiO2 scale at high temperature if the amount of oxygen in the ambient atmosphere is sufficient according to the following reaction: 5MoSi2 + 7O2(g)  7SiO2 + Mo5Si3 If the oxygen content at a specific temperature is too low, SiO(g) is more stable than SiO2 and the following reaction will occur instead: 2SiO2  2SiO(g) + O2(g) Then surface will be Si-deplated and finally, the base material will be exposed.
