  1. 1. Viability, feasibility and Sustainability of emission reducing solutions for Nordic wood stoves: Testing and evaluation : Degree project for Master in mechanical engineering with focus on innovative and sustainable product development

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Casper Berg; [2022]
    Keywords : Catalytic Filters; Variable filter deployment; Wood stove Emissions; Eco Design 2022; Reduced Emissions; Katalytiska filter; Varierande filter; Utsläpp från vedkaminer; Eco Design 2022; Reducerade utsläpp;

    Abstract : As of 2022 the European Union introduced a new Eco Design legislation which states emission limits for stoves sold in the EU. There are already requirements on emissions, but as both legislation are to be harder and there is a higher interest in Eco friendly products, there is an interest to study different ways to reduce the emissions from wood stoves.

  3. 2. Effect of ash on catalytic activity for passive regeneration of catalytic diesel particulate filter : Evaluation of ash deposition by laboratory ageing

    University essay from KTH/Kemiteknik

    Author : Gisela Engström; [2022]
    Keywords : Diesel Particulate Filter; Ash deposition; Laboratory Ageing; Catalytic Activity; Passive regeneration;

    Abstract : Askackumulering i dieselpartikelfilter är ett välkänt problem som resulterar i ett förhöjt mottryck och påverkad prestanda hos fordonet. Däremot ges sällan uppmärksamhet åt filtrets katalytiska aktivitet och hur det påverkas vid förekomst av avgasföroreningar. READ MORE

  4. 3. Wet etching of optical thin films

    University essay from JTH, Kemiteknik

    Author : Curt Edström; [2010]
    Keywords : Thin film; Wet etching; Optical coating; Physical vapour deposition;

    Abstract : Evaluation of the wet etching properties of several different thin film oxidesgrown by physical vapour deposition was performed in this work. MgO, Al2O3,SiO2, TiO2, HfO2 ZrO2 and Y2O3 were coated on two types of substrates; Si andborosilicate glass and etching tests were performed in different etchingsolutions. READ MORE
