2. 1. High temperature corrosion in a biomass-fired power boiler : Reducing furnace wall corrosion in a waste wood-fired power plant with advanced steam data

   Author : Yousef Alipour; Pamela Henderson; Peter Szalalos; Christofer Leygraf; Jan Froitzheim; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High temperature corrosion; Waterwalls; Power plant corrosion; NOx reducing enviroments; Biomass; Waste wood; Thermodynamic calculation modelling; corrosion-resistance alloy; Furnace wall corrosion; Högtemperaturekorrosion; Eldstadsväggar; kraftverks korrosion; låg Nox mijöer; biomassa; returträ; Termodynamisk modellering; korrosionsbeständighet legering; eldstadskorrosion;

   Abstract : The use of waste (or recycled) wood as a fuel in heat and power stations is becoming more widespread in Sweden (and Europe), because it is CO2 neutral with a lower cost than forest fuel. However, it is a heterogeneous fuel with a high amount of chlorine, alkali and heavy metals which causes more corrosion than fossil fuels or forest fuel. READ MORE

4. 2. Upscaling and Evaluation of Absorption Based Systems for Co-removal of NOx and SOx from Flue Gases

   Author : Jakob Johansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; absorption; gas-phase oxidation; scale-up; Emissions control; SOx; NOx; ClO2;

   Abstract : As long as combustion remains a vital part of the energy system, the removal of nitrogen oxides (NOx) will be a challenge that will need to be addressed. In addition, emissions of sulfur oxides (SOx) will be a problem as long as fuels such as coal and oil are used, as is envisaged in every road map suggested by the Intergovernmental Panel on Climate Change (IPPC).

5. 3. Oxy-Fuel Combustion - The Control of Nitrogen Oxides

   Author : Fredrik Normann; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxy-fuel; NOx; O2 CO2; combustion; emission; nitrogen oxides;

   Abstract : Oxy-fuel combustion is one of the main candidates for carbon dioxide capture from power plants. In oxy-fuel combustion, oxygen diluted with recycled flue gas oxidizes the fuel. The elimination of air-borne nitrogen generates a flue gas that mainly consists of carbon dioxide and water. READ MORE

6. 4. Absorption Based Systems for Co-removal of Nitrogen Oxides and Sulfur Oxides from Flue Gases

   Author : Jakob Johansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SOx; absorption; ClO2; sulfite oxidation; gas-phase oxidation; NOx; Emissions control; scale-up;

   Abstract : Enhanced control of nitrogen and sulfur emissions, found in many of industrial processes, is anticipated for decades to come. Stricter emission regulations require new technologies adapted to the new conditions at reasonable cost. READ MORE

7. 5. NOx formation in iron ore rotary kilns

   Author : Rikard Edland; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rotary kiln; Grate-Kiln process; emissions control; combustion chemistry; Nitrogen oxides;

   Abstract : Iron ore pellets are often produced using the so-called Grate-Kiln process, which is designed to oxidize the magnetite (Fe3O4) to hematite (Fe2O3) and to sinter the pellets so they can be used in steel manufacturing. The heat required for this process comes from the combustion of a pulverized fuel in a rotary kiln, involving the formation of a jet flame. READ MORE
