  1. 1. Experimental and Modeling Studies of Sulfur-Based Reactions in Oxy-Fuel Combustion

    Author : Daniel Fleig; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SO3; acid dew-point; coal combustion; oxy-fuel; sulfur; flue gas recycle; corrosion; Carbon capture and storage; H2SO4; SO2;

    Abstract : Oxy-fuel combustion is a technology for CO2 capture that is suitable for large-scale, coal-fired power plants. In this system, the combustion air is replaced by a mixture of O2 and recycled flue gases, so as to enrich for CO2 in the flue gas. READ MORE

  2. 2. The Fate of Sulfur during Oxy-Fuel Combustion

    Author : Daniel Fleig; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pulverized coal combustion; oxy-coal; SO3; Oxy-fuel; SO2; sulfur;

    Abstract : Oxy-fuel combustion, where air is replaced by O2 and recycled flue-gas to enrich combustion products, is one of the main CO2 capture technologies suitable for large-scale coal-fired power plants. The changed combustion conditions in oxy-fuel combustion influences the sulfur chemistry, which has recently been the subject of increased attention due to the importance of sulfur species in corrosion and flue-gas cleaning issues.

  3. 3. Strategies to reduce gaseous KCl and chlorine in deposits during combustion of biomass in fluidised bed boilers

    Author : Håkan Kassman; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Peat; KCl; Ammonium sulphate; IACM; Combustion of biomass; Sulphation; Chlorine in deposits;

    Abstract : Combustion of a biomass with an enhanced content of alkali and chlorine (Cl) can result in operational problems including deposit formation and superheater corrosion. The strategies applied to reduce such problems include co-combustion and the use of additives. READ MORE

  4. 4. Geology, alterations and mineral chemistry of the Tjårrojåkka Fe-oxide Cu-Au occurrences, northern Sweden

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Åsa Edfelt; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Abstract : The Tjårrojåkka area is located about 50 km WSW of Kiruna, northern Sweden, and hosts one of the best examples of spatially related Fe-oxide Cu-Au occurrences (the Tjårrojåkka-Fe and Tjårrojåkka-Cu). The bedrock, depositional environment and tectonic evolution of the area were studied through petrological, geochemical and geophysical-petrophysical investigations. READ MORE

  5. 5. Investigations of Chlorine-Induced High Temperature Corrosion of Steels

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Nicklas Folkeson; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sulphur; alkali; chlorine; field exposures; HCl-induced corrosion; high temperature corrosion; deposits.; chloride-induced corrosion; waste; 310S; HCl;

    Abstract : The high corrosivity of the fireside environment in waste and biomass fired boilers is commonly attributed to the presence of chlorine-containing compounds. Chlorine-induced high temperature corrosion is not well understood, however. READ MORE
