1. 21. Studies on the cement-bonded briquettes of iron and steel plant by-products as burden material for blast furnaces

   Författare :Maneesh Singh; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

   Sammanfattning : During the various stages of iron and steel production a number of iron bearing by-products are generated. These by-products can be made into cement- bonded agglomerates for use as burden material for blast furnaces. LÄS MER

3. 22. Recycling of metallurgical by-products within integrated iron and steelmaking : experimental studies of cold bonded by-product pellets

   Författare :Ryan Robinson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

   Sammanfattning : In recent years as costs for depositing dust and sludge generated in the iron and steel making industry have increased, due to lack of space and increasing environmental restrictions, the need to recycle these solid by- products to avoid depositing costs and to recover valuable metal fractions, is soon becoming a necessary reality. Cold bonded agglomeration is considered to be a well-suited alternative for recycling of steel industry by-product dust and sludge. LÄS MER

4. 23. Adoption of bioenergy technologies for a sustainable energy system

   Författare :Even Bjørnstad; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : A future sustainable energy system must achieve great improvements in energy efficiency and the energy supply must be based on renewable energy sources. Bioenergy will be an important part of this system. LÄS MER

5. 24. Wood fuel markets in Northern Europe : price formation and internationalization

   Författare :Olle Olsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : High fossil fuel prices and ambitions to reduce greenhouse gas emissions have increased demand for renewable energy and are changing wood fuel market structures. Wood fuels are to a rapidly growing degree used in industrial proportions and traded in commercial markets. LÄS MER

7. 25. Residential biomass combustion - emissions of organic compounds to air from wood pellets and other new alternatives

   Författare :Maria Olsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Burning; methoxy¬phenol; benzene; stove; ecolabel; oats; wheat straw; firewood; boiler; hydrocarbon; smoke; peat;

   Sammanfattning : It is important to increase the use of biofuels for residential heating in order to decrease the use of fossil fuels and their impact on global warming. The smoke from the combustion of biomass contains a large number of compounds, which to varying degrees can affect the environment and human health. LÄS MER
