2. 1. Combustion of agricultural residues : Application for Stirling micro-combined heat and power

   Author : Evelyn Cardozo; Torsten Torsten Fransson; Carlos Augusto Santos Silva; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Technology;

   Abstract : Access to energy services is crucial for the development of countries. Therefore, in developing countries, the access to modern conversion technologies would contribute to reduce the poverty, improve health services and promote the economy especially in rural areas. Around 2.5 billion people in these countries use biomass for cooking. READ MORE

4. 2. Studies of ash transformation processes in thermochemical co-conversion of phosphorus-rich manure and sludge with biomass residues

   Author : Gustav Häggström; Marcus Öhman; Anders Lagerkvist; Nils Skoglund; Flemming Jappe Frandsen; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sewage sludge; agricultural residues; forest residues; ash transformation; potassium; phosphorus; combustion; gasification; phosphorus recovery; Energy Engineering; Energiteknik;

   Abstract : Efficient use of resources and sustainable recovery of various materials are important to minimize the anthropogenic impact on the climate and environment. One such resource is the phosphorus (P) present in manure and sewage sludge. READ MORE

5. 3. Effects of Varying Combustion Conditions on PCDD/F Formation

   Author : Johanna Aurell; Stellan Marklund; Sukh Sidhu; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; dioxin; formation; PCDD; PCDF; MSW incineration; transient combustion; sulfur; memory effects; quench time; chlorine; combustion; polychlorinated dibenzothiophenes; NO; water; Environmental chemistry; Miljökemi;

   Abstract : Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are by-products emitted from combustion sources such as municipal solid waste (MSW) incineration plants. These organic compounds are recognized as toxic, bioaccumulative and persistent in the environment. READ MORE

6. 4. Fluidized bed combustion and gasification for phosphorus recovery by co-conversion of sewage sludge with biomass

   Author : Thomas Karl Hannl; Marcus Öhman; Matthias Kuba; Nils Skoglund; Mikko Hupa; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion; gasification; sewage sludge; agricultural residues; fluidized bed; ash chemistry; bed material; phosphorus; fuel design; Energy Engineering; Energiteknik;

   Abstract : In recent years, the thermal conversion of sewage sludge has proven its applicability for managing this inevitably generated waste. The viability arises from the concomitant features of recovering energy or valuable compounds, the breakdown of potentially harmful organic compounds, the separation or immobilization of heavy metals, and the formation of volume-reduced, sanitized residues.

7. 5. Residues from biochemical production of transport biofuels in Northern Europe : combustion properties and applications

   Author : Gunnar Eriksson; Bengt Johan Skrifvars; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

   Abstract : Residues from biochemical production of liquid transport biofuels will probably become available for energy use if more gasoline and diesel is substituted. For processes used in northern Europe they amount to 35-65 % of the feedstock energy and despite interest from energy companies, their fuel properties are largely unknown. READ MORE
