1. 1. 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.

4. 3. Mineralogical speciation of sulfur in acid sulfate soils from Luleå, Sweden

   University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

   Author : Niklas Gunnarsson; [2018]
   Keywords : acid sulfate soil; metal leakage; low pH; SEM; elemental sulfur; framboidal pyrite;

   Abstract : Marine sulfide – bearing sediments that oxidize when in contact with oxygen and leach outelements in high concentrations to small watercourses have been a problem for many years allover the world especially around the Bothnian Bay. The purpose of this study was to furtherinvestigate the sulfur mineralogy present in acid sulfate soils in the area of Luleå, Sweden. READ MORE

5. 4. Characterization of combinatorial Cu2ZnSnS4 thin films

   University essay from Uppsala universitet/Fasta tillståndets elektronik

   Author : Joakim Adolfsson; [2018]
   Keywords : Photovoltaics; Kesterite; Material science; Raman; Photoluminescence;

   Abstract : The kesterite Cu2ZnSnS4 (CZTS) is considered as a possible absorber layer in future photovoltaic (PV) applications. The abundance of its constituent elements along with the material being non-toxic and having a direct band gap of around 1.5 eV make it an attractive material for solar cell applications. So far, cells with an efficiency of 12. READ MORE

6. 5. Sulfur Addition to Reduce CO Emissions

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Fiona Yu; [2018]
   Keywords : Sulfur addition; emissions; carbon monoxide; Svaveldosering; kolmonoxid; utsläpp;

   Abstract : In autumn 2017, an experiment was conducted for the reduction of carbon monoxide (CO) emissions commissioned by Holmen Paper Braviken, one of the world’s most production-efficient paper mills. Digitalization has increased in recent years, which has resulted in a decreased demand for graphic paper. READ MORE
