1. 11. Ash chemistry and fuel design focusing on combustion of phosphorus-rich biomass

   Författare :Nils Skoglund; Dan Boström; Rainer Backman; Franz Winter; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phosphorus; biomass; combustion; ash chemistry; fuel design; ash transformation; phosphorus-rich; ash-forming elements; fuel fingerprint; ash transformation reactions; Lewis base; Lewis acid; oorganisk kemi; Inorganic Chemistry;

   Sammanfattning : Biomass is increasingly used as a feedstock in global energy production. This may present operational challenges in energy conversion processes which are related to the inorganic content of these biomasses. As a larger variety of biomass is used the need for a basic understanding of ash transformation reactions becomes increasingly important. LÄS MER

3. 12. The fate and ash transformations of phosphorus in combustion of biomass and sewage sludge

   Författare :Joel Falk; Marcus Öhman; Nils Skoglund; Dan Boström; Franz Winter; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

   Sammanfattning : The combustion of phosphorus (P)-rich biomass has a significant potential to increase the stock of biomass resources available for renewable heat and power production. In addition, the P-rich ashes have the potential as a fertilizer and could reduce the need for non-renewable P resources in agriculture. LÄS MER

4. 13. Sustainability measures in quicklime and cement clinker production

   Författare :Matias Eriksson; Rainer Backman; Dan Boström; Flemming Frandsen; Umeå universitet; []

   Sammanfattning : This thesis investigates sustainability measures for quicklime and cement clinker production. It is the aim of this thesis to contribute to the effort of creating a more sustainable modus of industrial production. LÄS MER

5. 14. Ash Behavior in Fluidized-Bed Combustion and Gasification of Biomass and Waste Fuels : Experimental and Modeling Approach

   Författare :Farzad Moradian; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluidized-bed; combustion; gasification; waste-derived fuels; biomass; ash-related problems; deposit; fouling; slagging; bed agglomeration; thermodynamic equilibrium modeling;

   Sammanfattning : Over the past few decades, a growing interest in the thermal conversion of alternative fuels such as biomass and waste-derived fuels has been observed among the energy-producing companies. Apart from meeting the increasing demand for sustainable heat and power production, other advantages such as reducing global warming and ameliorating landfilling issues have been identified. LÄS MER

7. 15. Aspects of alkali chloride chemistry on deposit formation and high temperature corrosion in biomass and waste fired boilers

   Författare :Markus Broström; Rainer Backman; Bengt-Johan Skrifvars; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; fysik; Physics; Electronics; elektronik;

   Sammanfattning : Combustion of biomass and waste has several environmental, economical and political advantages over the use of fossil fuels for the generation of heat and electricity. However, these fuels often have a significantly different composition and the combustion is therefore associated with additional operational problems. LÄS MER
