1. 16. Phasing out peat from a co-fired 50 MWth circulating fluidized bed boiler : A theoretical sulfation potential study

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

   Author : Axel Bergstrand; [2022]
   Keywords : Peat; corrosion; fuel mixture; CFB; circulating fluidized bed; S; alkali chlorides; Sulfur; additives; combustion; fuel design; alkali related corrosion;

   Abstract : The chemical company Perstorp AB has a 50 MWth circulating fluidized bed to supply the production plant with process steam. The fuel mixture used shows a large variation with about 20 different fuel fractions that can be divided into the categories, residue wood chips, sludge, forest fuel, animal waste, industrial residues, and peat.

3. 17. Owner's Salience in Unlisted Businesses

   University essay from Handelshögskolan i Stockholm/Institutionen för företagande och ledning

   Author : Gustav Henningsson; Jakob Lewander; [2022]
   Keywords : active ownership; stakeholder salience; corporate sustainability; unlisted businesses;

   Abstract : Shareholder activism in sustainability is increasingly being used to influence companies and their managers. Previous studies have focused on listed firms, but little theory has concentrated on unlisted assets. READ MORE

4. 18. Micromechanical modelling of creep in wooden materials

   University essay from Uppsala universitet/Tillämpad mekanik

   Author : Oskar Falkeström; Kevin Coleman; Malin Nilsson; [2021]
   Keywords : Creep; RVE; Homogenization; Honeycomb; Tracheid; Comsol Multiphysics; Micromechanical modelling; Orthotropic; Parametric study; S2 material; Norwegian Spruce; Scots Pine; Cell geometry;

   Abstract : Wood is a complex organic orthotropic viscoelastic material with acellular structure. When stressed, wood will deform over timethrough a process called creep. Creep affects all wooden structureand can be difficult, time-consuming and expensive to measure. For this thesis, a simple computer model of the woodenmicrostructure was developed. READ MORE

5. 19. Statistical analysis of firefighting and damage caused by fire in mid-rise timber-framed residential buildings compared to other construction types

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Thomas Berg; [2021]
   Keywords : Statistical analysis; timber-framed; residential; firefighting; damage caused by fire; PRONTO; NFID; linear regression; summary statistics; Technology and Engineering;

   Abstract : The contribution of greenhouse gas emissions in the production of construction materials has sparked a new interest and recent changes in building regulations regarding the use of renewables like wood as the main component in load-bearing elements. Recent regulation changes focus on allowing taller timber structures which bides the question of how to adequately maintain an acceptable level of fire protection considering the characteristically flammable properties of wood-based products.
