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

    Författare :Håkan Kassman; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nexus; Nexus approach; integrated resource assessments; CLEWs; integrated assessment modelling; knowledge transfer; sustainable development; Nexus; Nexus approach; integrerad resursbedömningar; CLEWs; integrerad bedömningsmodellering; kunskapsöverföring; hållbar utveckling; Energy Technology; Energiteknik;

    Sammanfattning : The last decade has seen the emergence of a new research theme - the study of the resources Nexus. The “Nexus” refers to considering the functioning of several systems simultaneously, as opposed to one, as the object of research. This perspective reasons that coherent decision-making needs to consider systems' interconnectedness. LÄS MER

  4. 33. Determinants of Corporate Environmental Information Management -Analytical Framework and Case Studies

    Författare :Johan Erlandsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; qualitative case studies; product chain; life cycle perspective; product-related environmental information; production-related environmental information; corporate environmental information systems; corporate environmental information management; life cycle assessment LCA ;

    Sammanfattning : Information about the environmental impact of production and products is a prerequisite to any attempt to mitigate environmental impact, either in production or in the choices of end consumers. There are however known problems regarding corporate environmental information management. LÄS MER

  5. 34. Exploring logistics actions enabling environmentally sustainable freight transport

    Författare :Vendela Santén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; co-operation; freight transport; actions; load factor; logistics; actors’ perspectives; sustainability; environment;

    Sammanfattning : To curb unsustainable freight transport trends; such as transport growth, larger dependency on road transport and generally an increased share of greenhouse gas emissions from the sector, actions needs to be taken among actors in the logistics system. The purpose of this thesis is to explore logistics actions that enable environmentally sustainable freight transport. LÄS MER

  7. 35. Reducing Carbon Emissions From Natural Gas-fired Power Plants – Biomass, Concentrated Solar and Carbon Capture

    Författare :Erik Pihl; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon capture and storage; bioenergy; biofuels; optimisation; modeling; solar thermal power; resource limitations; thermo-economic assessment;

    Sammanfattning : In this thesis, possibilities to reduce emissions from combined cycle gas turbine (CCGT) plants are evaluated. The evaluation is done from two perspectives: techno-economic analysis, and analysis of the resource and integration potentials. LÄS MER
