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.

3. 2. 3D Printed NovelZeolite 13X - Magnesium ChlorideComposites for Ammonia Storage

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Rafael Acosta Laisequilla; [2019]
   Keywords : Ammonia absorption 3D printing Zeolites;

   Abstract : In today’s world regulations to reduce vehicle emissions are only gettingtougher, from said regulations the concept of a Selective Catalytic Reduction(SCR) unit was born, designed to provide a healthy dose of ammonia (NH3)to reduce the NOx compound into harmless components such as water andnitrogen. In this thesis novel approaches where investigated, by combiningthe fast physical absorption and desorption properties of a highly porous ma-terial such as zeolites with the high storage capacity of metal chlorides wecan potentially improve NH3 dosing in the low temperature operating range,such as when vehicles have just been turned on.

4. 3. Thermodynamic Equilibrium Prediction of Corrosion Tendency in Fluidized-Bed Combustion of Solid Waste

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Aida Hosseinian; [2017]
   Keywords : Waste to Energy; Fluidized Bed Boiler; Combustion; Corrosion; Factsage; Chemical Fractionation; Waste-derived Fuel;

   Abstract : Global warming and air pollution are two issues of greatest concerns to human life in recent years. Environmental concerns and econimal/political independency of fossil fuels have been the driving force of developing interest in renewable resources of energy for many countries. READ MORE

5. 4. Industrial Pilot Scale Leaching and Recovery of Zinc from Waste-to-Energy Fly Ash using Scrubber Liquids

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Manuela Wagner; [2016]
   Keywords : pilot plant; zinc recovery; fly ash; WtE; scrubber liquids; leaching; precipitation; chlorides;

   Abstract : Previous studies from laboratory experiments and a similar process at a plant in Switzerland, led to the pilot plant project at Renova AB, which will be described in this master thesis. In cooperation with Götaverken Miljö AB it was investigated if fly ash, produced at the Renova Waste-to-Energy plant in Gothenburg, could be treated with own scrubber liquids in order to recover zinc.

6. 5. Investigation of Galvanic Corrosion between Graphite Gaskets and Stainless Steel Flanges

   University essay from Uppsala universitet/Strukturkemi

   Author : Martin Bengtsson; [2015]
   Keywords : Galvanic Corrosion;

   Abstract : At Forsmark, several cases of suspected galvanic corrosion have been detected and believed to be caused by an inappropriate use of graphite gaskets in brackish water. This report studies the likelihood of galvanic corrosion between the graphite gasket and stainless steels and aims to be a reference when investigating galvanic corrosion in the future. READ MORE
